Find the solution of 3x-2=13.

3x-2=13

Transposing -2 to RHS, we have

Or                              3x=13+2

                                 3x=15

Or                               x=               (Dividing both sides by 3)

Or                               x=5

5x-9=8

Transposing 9 to RHS, we have

                                         5x=8+9=17

 ∴                                           x=                     (Dividing both sides by 5)

x = -12

x = 5
