<u>ANSWER</u>

<u>EXPLANATION</u>
The given compound inequality is

We need to simplify this inequality so that we can obtain x standing alone between the inequality signs.
We add 6 through out the inequality.

This simplifies to:

We now divide through by -3 and reverse the inequality sign.

We now simplify to get:

Remember PEMDAS, you have to simplify the exponent first.
