Solving One Step Equations with Whole Numbers

The video tutorial explains how to solve linear equations by isolating the variable on one side of the equation. It provides two examples: solving x + 9 = 24 by subtracting 9 from both sides, and solving x - 7 = 32 by adding 7 to both sides. The tutorial emphasizes the importance of performing the same operation on both sides of the equation to maintain equality and checks the solutions by substituting the values back into the original equations.

What is the primary goal when solving a linear equation?

• To perform addition on both sides
