Linear Equations in One Variable

Short Answer Type

61.
Solve the following equation and check your results.

5x + 9 = 5 + 3x

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
