Solving Two-Step Linear Equations

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 emphasizing the importance of maintaining equality by performing the same operation on both sides of the equation.

What is the primary goal when solving a two-step linear equation?

• To find the sum of all terms

• To make both sides equal zero

• To isolate the variable

• To eliminate all numbers
