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.
