Answer:

Step-by-step explanation:

Multiply the numbers     2 ( x - 11 ) * 2 = 128

                                          4 ( x - 11 ) = 128

Distribute              4 ( x - 11 ) = 128

                                 4x - 44 = 128

Add 44 to both sides              4x - 44 = 128

                                                    4x - 44 + 44 = 128 + 44

Simplify                        - Add the numbers    

                                        4x - 44 + 44 = 128 + 44

                                            4x = 128 + 44

                                        - Add the numbers

                                  4x = 128 + 44

                                   4x = 172

Divide both sides by the same factor                    4x = 172

                                                                                 4x/4 = 172/4

Simplify

-     Cancel terms that are in both the numerator and denominator

                                                                4x/4 = 172/4

                                                                     x = 172/4

-Divide the numbers

                                                           x = 172/4

                                                             x = 43
