Уравнение  x-3/4=5/72(x-8)+4=5*(3-x)

х = 5/7 + 3/4                                             2х - 16 + 4 = 15 - 5хх = 20/28 + 21/28                                     2х + 5х = 15 + 16 - 4х = 41/28 = 1 13/28                                  7х = 27                                                                 х = 27 : 7 = 3 6/7
