The original function is .

Write as or

First solve the case . \ \

                    (Add 2 to each side)

                          (Apply additive inverse property: )

                                (Apply additive identity property: )

                                      (Add: )

                                 (Divide each side by 3)

                                     (Cancel common terms)

                                        (Divide: )

Next solve the case . \ \

                (Add 2 to each side)

                      (Apply additive inverse property: )

                            (Apply additive identity property: )

                                  (Add: )

                             (Divide each side by 3)

                                  (Cancel common terms)

                                 (Divide: )

First, draw a number line.

To graph the solutions set, mark the numbers and 2 on number line.

The solution set is .
