Question

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? (2 points)

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.

Answer 1

At the end there's something you have to do when dividing the negative. What is it? I'll give u a hint it has to do with the sign.

Answer 2

flip it

Answer 3

Yep. I hope this helps.

Answer 4

thank you
