Introduction

Solving for x in a linear equation is a fundamental concept in mathematics, and it's essential to understand how to isolate the variable in a given equation. In this article, we'll focus on solving for x in the equation $6x - 8 = 22$. This equation is a linear equation, and we'll use algebraic techniques to isolate the variable x.

Understanding the Equation

The given equation is $6x - 8 = 22$. This equation is a linear equation, and it can be written in the general form $ax + b = c$, where a, b, and c are constants. In this case, a = 6, b = -8, and c = 22.

Step 1: Add 8 to Both Sides

To solve for x, we need to isolate the variable. The first step is to add 8 to both sides of the equation. This will eliminate the negative term on the left-hand side of the equation.

6x - 8 + 8 = 22 + 8
6x = 30

Step 2: Divide Both Sides by 6

Now that we have the equation $6x = 30$, we need to isolate the variable x. To do this, we'll divide both sides of the equation by 6.

(6x) / 6 = 30 / 6
x = 5

Conclusion

In this article, we solved for x in the equation $6x - 8 = 22$. We used algebraic techniques to isolate the variable x, and we arrived at the solution x = 5. This solution satisfies the original equation, and it's the only solution to the equation.
