The video tutorial explains how to solve two-step equations by isolating variables on one side of the equation and numbers on the other. It emphasizes the importance of performing the same operations on both sides of the equation. The tutorial includes three example problems, demonstrating the use of subtraction, multiplication, and division to solve equations with variables and fractions.

What is the first step in solving a two-step equation?

• Add the same number to both sides

• Multiply both sides by the same number

• Isolate the variable on one side

• Divide both sides by the same number
