**Solving Inequalities by Multiplication and Division**

Lesson 6-2 Solving Inequalities by Multiplication and Division

2
Definition Multiplication Property of Inequalities- If each side of a true inequality is multiplied by the same positive number, the resulting inequality is true. If each side of a true inequality is multiplied by the same negative number, the direction of the inequality symbol must be reversed so that the resulting inequality is also true.

9
Definition Division Property of Inequalities- If each side of a true inequality is divided by the same positive number, the resulting inequality is true. If each side of a true inequality is divided by the same negative number, the direction of the inequality symbol must be reversed so that the resulting inequality is also true.
