how do you multiply and divide inequalities and work the problem out???

Numbers can be added or subtracted from both sides of an inequality without chaning its dircction.

The same goes for multiplying or dividing both sides by POSITIVE numbers.
If a negative number is multiplied by or divided into an inequality, the direction of the > or < sign must change.
Use these rules to get only the unknown (x) on one side of the inequality, and you will have solved it.
