Andrew solved the following inequality, and his work is shown below:
−4(x + 8) ≤ −2x + 50
−4x − 32 ≤ −2x + 50
−2x − 32 ≤ 50
−2x ≤ 82
x ≤ −41
What mistake did Andrew make in solving the inequality?
NEEED HELP PLZZ WILL GIVE BRAINIEST IF RIGHT
A He did not make a mistake.
B When dividing by −2, he did not change the direction of the sign.
C He added 2x to both sides when he should have subtracted.
D He added 32 to both sides when he should have subtracted.
