Solving Two-Step Equations

The video tutorial covers solving two-step equations by isolating the variable using inverse operations. It provides examples such as 3X + 4 = 10, 13 = 5X - 2, 2X - 3 = 5, -27 + 3X = -12, and 21 = 6X - 3. Each example demonstrates the process of using addition, subtraction, multiplication, and division to isolate the variable and solve the equation.

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

• Isolate the variable on one side

• Divide both sides by a number

• Add a constant to both sides

• Multiply both sides by the variable
