Solving for x: A Comprehensive Guide

Hey guys! Let's dive into the world of algebra and learn how to solve equations, particularly those involving fractions. It might seem tricky at first, but with a clear understanding of the steps and a bit of practice, you'll be solving for x like a pro. This article will break down the process of solving equations like βˆ’114x+72=6x\frac{-11}{4x} + \frac{7}{2} = \frac{6}{x} step-by-step, making it easy to understand and follow along. We'll cover everything from the basics of isolating x to handling fractions and simplifying the equation. So, grab your pencils and let's get started. Solving for x is a fundamental skill in mathematics, used in everything from basic algebra to advanced calculus, so let's start with our first concept.

Understanding the Basics: Equations and Variables

Alright, before we jump into the equation, let's make sure we're all on the same page. What exactly is an equation? Simply put, an equation is a mathematical statement that shows two expressions are equal. It's like a balanced scale; whatever you do to one side, you must do to the other to keep it balanced. The goal when solving an equation is to find the value of the unknown variable, which is usually represented by a letter like x. This value makes the equation true. In our case, the variable we are trying to solve is x. Think of x as a hidden number, and our job is to uncover it. To solve for x, we use algebraic manipulations to isolate it on one side of the equation. This means we perform operations (like adding, subtracting, multiplying, or dividing) on both sides of the equation until x stands alone. The steps involved in solving equations can vary depending on the complexity of the equation, but the underlying principle remains the same: maintain the balance and isolate the variable. The process involves multiple steps, including eliminating fractions (if there are any) and simplifying the equation to its basic form. We aim to find the precise value of x that satisfies the initial equation. Therefore, understanding the fundamentals of algebraic principles is extremely important for our topic. So let's recap, an equation is a statement of equality and the variable is an unknown that we are trying to find. This should get you started, let's now tackle some fractions.

Tackling Fractions: Clearing the Denominators

Now, let's get down to the nitty-gritty of solving our equation: βˆ’114x+72=6x\frac{-11}{4x} + \frac{7}{2} = \frac{6}{x}. As you can see, this equation involves fractions, and fractions can sometimes make things a bit more complicated. So, the first step is often to get rid of those pesky fractions by finding a common denominator and multiplying each term in the equation by it. This is a super important step because it simplifies the equation and makes it easier to work with. How do we find the common denominator? Well, the common denominator is the smallest number that all the denominators (in this case, 4x, 2, and x) divide into evenly. Looking at our denominators, we have 4x, 2, and x. The least common multiple (LCM) of these denominators is 4x. So, we'll multiply every term in the equation by 4x. This will eliminate all the denominators, which makes the equation much easier to solve. When multiplying by 4x, remember to apply it to every term on both sides of the equation to maintain balance. This is like the golden rule of equations: whatever you do to one side, you have to do to the other. By multiplying each term by 4x, we transform the equation into a simpler form, which is now ready for further simplification. This step is designed to eliminate fractions, making it significantly easier to isolate and solve for the unknown variable, x. It's a fundamental trick that streamlines the entire solving process. Remember this step when you get a fraction, multiply by the least common multiple.

Step-by-Step Solution

Let's get into the step-by-step solution to solve our equation. Okay, now that we know the basics, let's break down the process of solving for x in the equation βˆ’114x+72=6x\frac{-11}{4x} + \frac{7}{2} = \frac{6}{x} step-by-step. Follow along, and you'll see how easy it can be! Remember, the goal is to isolate x on one side of the equation. First, clear the fractions. As we discussed, we'll multiply every term in the equation by the least common multiple (LCM) of the denominators, which is 4x. This gives us: 4x * (βˆ’114x\frac{-11}{4x}) + 4x * (72\frac{7}{2}) = 4x * (6x\frac{6}{x}). Now, we simplify each term by canceling out common factors: -11 + 14x = 24. Next, isolate the variable term. We want to get all the terms with x on one side and the constants on the other side. So, we'll move the constant term (-11) to the right side of the equation by adding 11 to both sides: 14x = 24 + 11. Now, we simplify: 14x = 35. Finally, solve for x. To isolate x, we divide both sides of the equation by 14: x = 3514\frac{35}{14}. We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 7: x = 52\frac{5}{2}. Therefore, the solution to the equation βˆ’114x+72=6x\frac{-11}{4x} + \frac{7}{2} = \frac{6}{x} is x = 52\frac{5}{2}. This process illustrates how we used to get rid of fractions and isolate the variable in an equation. Make sure you understand each step.

Verification of Solution

Alright, you've solved for x, but how do you know if your answer is correct? It's always a good idea to check your solution by plugging it back into the original equation. This is like a safety net; it ensures that your solution satisfies the equation and that you haven't made any mistakes along the way. To verify our solution, we'll substitute x = 52\frac{5}{2} back into the original equation: βˆ’114βˆ—(52)+72=6(52)\frac{-11}{4*(\frac{5}{2})} + \frac{7}{2} = \frac{6}{(\frac{5}{2})}. Let's simplify this step-by-step. First, we simplify the denominators: βˆ’1110+72=125\frac{-11}{10} + \frac{7}{2} = \frac{12}{5}. Now, let's get a common denominator to add the fractions on the left side, which is 10: βˆ’1110+3510=125\frac{-11}{10} + \frac{35}{10} = \frac{12}{5}. Combine the fractions on the left side: 2410=125\frac{24}{10} = \frac{12}{5}. Simplify the fraction on the left side: 125=125\frac{12}{5} = \frac{12}{5}. Since both sides of the equation are equal, our solution x = 52\frac{5}{2} is correct. Verification is a crucial step in problem-solving. It not only confirms the correctness of the solution but also enhances your understanding of the equation. Always take the time to verify your answers, it helps develop your problem-solving skills.

Common Mistakes to Avoid

It's easy to make mistakes when you're first learning to solve equations. So, let's talk about some common pitfalls and how to avoid them. One common mistake is forgetting to multiply every term in the equation by the common denominator when clearing fractions. Remember, you must apply the operation to each term on both sides of the equation to keep it balanced. Another common error is making arithmetic mistakes when simplifying expressions. Always double-check your calculations, especially when dealing with fractions and negative signs. Another mistake is in distributing multiplication across terms within parentheses. Make sure to multiply the term outside the parentheses by every term inside the parentheses. Also, pay attention to the order of operations (PEMDAS/BODMAS) to ensure calculations are performed in the correct order. These steps will help you catch errors early and ensure you arrive at the correct solution. By understanding these potential issues, you can work to improve the accuracy of your solution. These might seem small, but these are crucial to ensure you are getting the correct answer.

Tips for Success
