Inequalities: Addition and Subtraction Techniques

• If the same number is added or subtracted from both sides of an inequality, the resulting inequality has the same solutions as the original one.

• Use set builder notation to describe the solution set of an inequality.

• The solutions to inequalities can also be shown by shading the solution set on a number line. Endpoints should be drawn as solid dots if they are part of the solution set, and open circles otherwise.
