First solve the case .

                    (Subtract 3 form each side)

                          (Apply additive inverse property: )

                                (Apply additive identity property: )

                                     (Subtract: )

Next solve the case .

                (Subtract 3 form each side)

                      (Apply additive inverse property: )

                            (Apply additive identity property: )

                                  (Subtract: )

First, draw a number line.

To graph the solutions set, mark the numbers –8 and 2 on number line.
