Step-by-step explanation:

Step 1: Define

Identify

-2(y - 4) = 18

Step 2: Solve for y

  1. [Distributive Property] Distribute -2:                                                                -2y + 8 = 18
  2. [Subtraction Property of Equality] Subtract 8 on both sides:                        -2y = 10
  3. [Division Property of Equality] Divide -2 on both sides:                                y = -5
