Answer:

He didn't change the direction of the inequality when he divided both sides by -2.

Explanation:

Let's go through each step and see.

First step: They distribute and they did so correctly. -4(x+8)=-4x-32.

Second step: They added 2x on both sides.

Third step: They added 32 on both sides.

Fourth step: The divide both sides by -2 correctly but since this is inequality you must flip the sign.

For example 3>2 but if you multiply both sides by -1 or divide both sides by -1 you get -3<-2.

You have to flip the sign whenever you multiply or divide both sides of inequality by negative number.
