Andre tried to solve the equation 1/4 (x+12) = 2 what was his mistake?

Andre steps:

1/4x=-10

X = - 40

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.
