Solve the following equation and check your results.

5x + 9 = 5 + 3x

Solution

5x + 9 = 5 + 3x
Transposing 9 to RHS, we have
                                    5x = 5 + 3x - 9
or                                  5x = -4 + 3x
Transposing 3x to LHS, we have
                           5x - 3x = -4
or                                 2x = -4
Dividing both sides by 2, we have
                               x equals space fraction numerator negative 4 over denominator 2 end fraction equals negative 2
or                              x = -2
