10-27.

Solve each equation. Explain or justify your steps for part (b). Homework Help ✎

  1. Simplify both sides.
    2x + 2 + 3 = 3x − 3
    2x + 5 = 3x − 3

    Add 3 to both sides leave only one constant.
    2x + 5 + 3 = 3x − 3 + 3
    2x + 8 = 3x
    Then take 2x from both sides to isolate x.
    2x + 8 −2x = 3x − 2x

    x = 8
