Solving Two-Step Inequalities

A two-step inequality is an inequality that contains two operations such as addition and division or subtraction and multiplication.
Solving two-step inequalities is very similar to solving two-step equations. Use inverse operations to isolate the variable. A difference is that in inequalities, when multiplying or dividing each side by a negative number, the inequality sign must be reversed.
