$Incorrectly isolating the fraction$

Introduction

Solving for x in an equation is a fundamental concept in mathematics, and it is essential to understand how to isolate the variable in a given equation. In this article, we will focus on solving for x in the equation $\frac{x}{3} + 12 = 23$ . This equation involves fractions and requires a step-by-step approach to isolate the variable x.

Understanding the Equation

The given equation is $\frac{x}{3} + 12 = 23$ . To solve for x, we need to isolate the variable x on one side of the equation. The equation involves a fraction, which can be challenging to work with. However, by following a systematic approach, we can simplify the equation and solve for x.

Step 1: Subtract 12 from Both Sides

To isolate the fraction $\frac{x}{3}$ , we need to subtract 12 from both sides of the equation. This will help us eliminate the constant term on the left side of the equation.

$\frac{x}{3} + 12 - 12 = 23 - 12$

Simplifying the equation, we get:

$\frac{x}{3} = 11$

Step 2: Multiply Both Sides by 3

To eliminate the fraction, we need to multiply both sides of the equation by 3. This will help us get rid of the denominator and isolate the variable x.

$\frac{x}{3} \times 3 = 11 \times 3$

Simplifying the equation, we get:

$x = 33$

Conclusion

In this article, we solved for x in the equation $\frac{x}{3} + 12 = 23$ . By following a systematic approach, we were able to isolate the variable x and find the solution. The correct answer is $x = 33$ . This equation involves fractions, and it is essential to understand how to work with fractions when solving for x.
