Best ResponseYou've already chosen the best response.0You can solve an inequality the same way you solve an equation with one difference. When you multiply or divide both sides by a negative number, the inequality sign changes direction.

Best ResponseYou've already chosen the best response.0You want to isolate x. That means you need to get rid of the 7 from the left side first. Step 1. Subtract 7 from both sides. What do you get?

Best ResponseYou've already chosen the best response.0Great. Remember, we're trying to isolate x. Now I see that x is being multiplied by 9. We need x alone, so we need to divide both sides by 9. Remember the rule above that the inequality sign must flip when you multiply or divide by a negative number.
