Eduardo solved the following inequality, and his work is shown below: -5(x + 4) + 21 2 -3 + 4(x - 8)
-5x - 20 + 21 2 -3 + 4x - 32
-5x + 1 2 4x - 35
-9x 2 -36
x 24
what mistake did Eduardo make in solving the inequality? (2 points)
When dividing by -9, he did not change the 2 to s.
He subtracted 4x from both sides when he should have added 5x.
He subtracted 1 from both sides when he should have added 36.
He did not make a mistake.
