Write AND Solve the expression.

The sum of 9 and 3 then multiplied by 5

   5(x+ 3) = 9x - 13.

                                                 5x + 15 = 9x - 13

                                                -4x + 15 = -13

                                                -4x = -28

                                                   x = 7
