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 5 lx - 52
-5x < -45

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 s to 2.
He added 7 to both sides when he should have added 52.
He did not make a mistake.
