Пошаговое объяснение:

1/2 : (5/6х - 1/3) - 1/4 = 1/8

1/2 : (5/6х - 1/3) = 1/8 + 1/4

1/2 : (5/6х - 1/3) = 1/8 + 2/8

1/2 : (5/6х - 1/3) = 3/8

5/6х - 1/3 = 1/2 : 3/8

5/6х - 1/3 = 1/2 * 8/3

5/6х - 1/3 = 8/6

5/6х - 1/3 = 4/3

5/6х = 4/3 + 1/3

5/6х = 5/3

х = 5/3 : 5/6

х = 5/3 * 6/5

х = 6/3

х = 2
