x=ind tickets
y=coup. tickets                   x = 38 + y ← # of ticket equation
                                           3x + 5y =730 ← $ of equation

 3(38+y) + 5y = 730
 114 + 3y + 5y = 730
    114 + 8y =730
   -114       = -114 →    8y =616 = y= 77  →  x= 38 +y → x=38 + 77 → x =115
                                                  (115,77)
                        15 individual tickets and 77 couple tickets
