Dik. sistem persamaan 3x + 2y = 8 dan x - 5y = 37 = 0. Tentukan nilai dari 6x = 4y

3x + 2y = 8                 ------> 3x + 2y = 8
  x - 5y  = 37 dikali 3   ------> 3x -15y = 111
                                             ------------------- -
                                                   17y = - 103
                                                       y = - 6,06
x - 5y = 37
x - 5(-6,06) = 37
x = 37 + 30,3
   = 67,3

6x = 4y
6x - 4y = 6(67,3) - 4(6,06)
            = 403,8 - 24,24
            = 379,56
