Peшите уравнения:

2 - (3x-7) / 4 + (x+17) / 5=0

(4x+7) / 5 + (3x-2) / 2 - (5x-2) / 2=32

( - 3x + 9) / 4 = - (x + 17) / 5

( - 3x + 9) / 4 = ( - x - 17) / 5

5 ( - 3x + 9) = 4 ( - x - 17)

- 15x + 45 = - 4x - 68

- 15x + 4x = - 45 - 68

- 11x = - 113

11x = 113

x = 113/11

x = 10 целых 3/11

приводим к общему знаменателю и решаем:

(8x + 14 + 15x - 10 - 25x + 10) / 10 = 32

( - 2x + 14) / 10 = 32/1

- 2x + 14 = 32 * 10

- 2x + 14 = 320

- 2x = 320 - 14

- 2x = 306

2x = - 306

x = - 306/2

x = - 153
