\ \

The inequality is . \ \

Solve the inequality. \ \

                         (Original inequality) \ \

        (Add to each side) \ \

                        (Apply additive inverse property: ) \ \

                                (Add: ) \ \

                           (Divide each side by ) \ \

                                    (Cancel common terms) \ \

                                          (Multiply each side by negative one and flip the symbol) \ \

The graph of the solution set on a number line diagram. \ \

A circle means that this point is not included in the solution set.

Check solution for -value \ \

Case(i): \ \

                       (Original inequality) \ \

                    (Substitute ) \ \

                      (Multiply) \ \

                              (Add: ) \ \

Therefore, is true inequality. \ \

Case(ii): \ \

                      (Original inequality) \ \

                   (Substitute ) \ \

                     (Multiply) \ \

                             (Add: ) \ \

Therefore, is false inequality. \ \

\ \

The solution set of the inequality is .
