Step-by-step explanation:

Step 1: Define

-8 = 2y - 2

Step 2: Solve for y

  1. [Addition Property of Equality] Add 2 on both sides:                                  -6 = 2y
  2. [Division Property of Equality] Divide 2 on both sides:                               -3 = y
  3. Rewrite/Rearrange:                                                                                         y = -3

Step 3: Check

Plug in y into the original equation to verify it's a solution.

  1. Substitute in y:                                                                                                -8 = 2(-3) - 2
  2. Multiply:                                                                                                           -8 = -6 - 2
  3. Subtract:                                                                                                          -8 = -8

Here we see that -8 does indeed equal -8.

∴ y = -3 is the solution to the equation.
