Mastering Two Step Equations Basics

This video tutorial introduces solving two-step linear equations by isolating the variable. It covers the basic steps: adding or subtracting to isolate the variable term, then multiplying or dividing to solve for the variable. The video provides five examples, demonstrating each step in detail, and emphasizes the importance of performing the same operation on both sides of the equation to maintain equality.

What is the primary goal when solving any linear equation?

• To simplify the equation

• To isolate the variable

• To balance both sides of the equation

• To find the value of the variable
