Solve the following equation and check your results.

2x - 1 = 14 - x

2x - 1 = 14 - x

Transposing (-1) to RHS, we have

                             2x = 14 -x +1

or                           2x = 15 -x

Transposing (-x) to LHS, we have

                              2x + x = 15

or                                    3x = 15

Dividing both sides by 3, we have

                                     $straight x equals 15 over 3 equals 5$

∴ x = 5
