When solving inequalities the process you use is exactly the same as when solving equations with one major exception. Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own. But these things will change direction of the inequality if multiplying or dividing both sides by a negative number is needed.

Solutions for inequalities are expressed in three ways: Set Notation, Interval Notation and Graphing

Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own. But these things will change direction of the inequality: Multiplying or dividing both sides by a negative number.
