Пошаговое объяснение:

(3x-1)/2 - 9 = -(2-x)/6    |*6

3(3x - 1) - 9*6 = -2 + x

9x - 3 - 54 = -2 + x

9x - 57 = -2 + x

9x - x = 57 - 2

8x = 55

x = 55:8

x = 6цел. 7/8

==================

(x+3)/7 - 1 - (3-x)/14 = 0     |*14

2(x + 3) - 1*14 - 3 + x = 0

2x + 6 - 14 - 3 + x = 0

3x - 11 = 0

3x = 11

x = 11 : 3

x = 3цел. 2/3
