Average=Sum of our 4 numbers + unknown number of x
                ____________________________________
                                          Total Numbers

                      5
Cross Multiply
___________
3 + 19 + 8 + 32 +  = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
