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?

He did not make a mistake.
When dividing by −2, he did not change the direction of the sign.
He added 2x to both sides when he should have subtracted.
He added 32 to both sides when he should have subtracted.
