    Step-by-step explanation:

    1. 1/4 (x + 12) = 2 - first isolate X'

    - 12 - 12

    2. 1/4 (x) = - 10 - 1/4 since its a fraction, you'll have to subtract not divide

    -1/4 - 1/4

    3. x = - 10.25

    Andre did the first step correctly, but on the second step he just divided 1.4 by - 10, instead of subtract 1/4 from both sides.
