Solve the following equation:
y + 3 = 10
y + 3 = 10
Transposing 3 to RHS, we have
                                      y = 10 - 3
∴                                     y = 7
Solve the following equation:
6 = z + 2
6 = z + 2
Transposing 2 to LHS, we have
                                    6 - 2 = z
or                                      4 = z
∴                     z = 4
Solve the following equation:
6 = z + 2
