Andrew solved the following inequality, and his work is shown below:


−4(x + 8) + 25 ≤ −2 + 1(x − 50)

−4x − 32 + 25 ≤ −2 + 1x − 50

−4x − 7 ≤ 1x − 52

−5x ≤ −45

x ≤ 9


What mistake did Andrew make in solving the inequality?


A-He subtracted 1x from both sides when he should have added 4x.

B-When dividing by −5, he did not change the ≤ to ≥.

C-He added 7 to both sides when he should have added 52.

D-He did not make a mistake.
