Two-Step Inequalities

Two step inequalities

Objective: solve inequalities using two inverse operations

solution or not?

x > -15

-15

x=-23 x = 0 x=-15

solving an equation is the same as solving an inequality.except...

Remember to flip that sign when you multiply or divide by a negative! .

solve and graph the solution set.

16 < -5N+1

solve and graph the solution set.
