Решите уравнение:
2 2/3/х+1/3=1 1/2/х-1 1/8

х = 3.

Пошаговое объяснение:

2 2/3 * 1 1/8 = 8/3 * 9/8 = 1/1 * 3/1 = 3/1 = 3;

1 1/2 * 1/3 = 3/2 * 1/3 = 1/2 * 1/1 = 1/2.

2 2/3х - 1 1/2х = 1/2 + 3;

2 4/6х - 1 3/6х = 3 1/2;

1 1/6х = 3 1/2;

х = 3 1/2 : 1 1/6;

х = 7/2 : 7/6;

х = 7/2 * 6/7;

х = 1/1 * 3/1;

х = 3/1;

х = 3.

ответ: х = 3.
