решите уравнение плиз очень надо 2(1 1/7-х)-3 1/14 = -2 5/7

2(1 1/7-х)-3 1/14 = -2 5/72 2/7-2х-3 1/14 = -2 5/7-2х=-2 5/7-2 2/7+3 1/14-2х=-2 1/14х=2 1/14:2х=1 1/28

2(1 1/7-х)-3 1/14 = -2 5/72(8/7 - x) - 43/14 = - 19/716/7 - 2x - 43/14 = -19/732/14 - 28/14x - 43/14 = -38/14-28x = - 38 - 32 + 43      - 28x = 27      x = -27/28
