Question

PLEASE HURRY

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)

Question 3 options:

1)

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

2)

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

3)

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

4)

He did not make a mistake.

Answer 1

Answer 2) When dividing by -5, he did not change the
`\leq` to
`\geq`.

Explanation:

If you divide or multiply a negative, you ALWAYS change the sign to its opposite.

Hope this helps! :)
