Two-Step Equation Inverse Operations Quiz (Multiple Choice)

Directions: For each equation below, choose the FIRST inverse operation you should perform to begin isolating the variable by eliminating the constant term. Also select the correct form of how the equation should look like after that operation is applied. 1. 4y + 7 = 39 What is the first inverse operation you should perform, and what would the equation look like after applying it?

• Subtract 7 → 4y = 32

• Add 7 → 4y + 14 = 39

• Divide by 4 → y + 1.75 = 9.75

• Multiply by 4 → 16y + 28 = 156
