You solve an inequality in the same way as you would solve an equality (equation).

The only difference is that if you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign.

Thus, if you have

-3x < 9

to find x, you need to divide by -3. That is a negative number so

-3x/(-3) > 9/(-3) reverse inequality

x > -3
