The answer is x=6.     9x-6=3x+30

                                    9x-3x-6=3x-3x+30

                                     6x-6=0 +30

                                     6x-6 + 6= 0 + 30 +6

                                     6x=36

                                      6x/6=36/6

                                         x=6
