Answer:

1. The mistake he made was in Step #2. He subtracted 10 from -6 and 10 but he didn't subtract 10 from 18.

2. The correct answer should be -16 ≤ x < 8

Hope this helps : )

Explanation:

Whatever you do on one side of an inequality/equation, you must do the same thing to the other side(s).

To get the correct answer he must subtract 10 from 18 which equals 8.

The final compound inequality is -16 ≤ x < 8
