Solve the following equation and check your results.

8x + 4 = 3 (x-1) +7

8x + 4 = 3 (x-1) +7

or                          8x + 4 = 3x - 3 + 7

or                          8x + 4 = 3x + 4

Transposing 4 to RHS, we have

                             8x = 3x + 4 - 4

Transposing 3x to LHS, we have

                              8x - 3x =0

or                                  5x = 0

∴ x = 0
