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?
He subtracted 1x from both sides when he should have added 4x.
When dividing by −5, he did not change the ≤ to ≥.
He added 7 to both sides when he should have added 52.
He did not make a mistake.
I got B
