Реши уравнение 2 1/2x - 1 1/3x = 4 2/3

2 целых 1 / 2 * x - 1 целая 1 / 3 * x = 4 целых 2 / 3;

(2 * 2 + 1) / 2 * x - (1 * 3 + 1) / 3 * x = (4 * 3 + 2) / 3;

(4 + 1) / 2 * x - (3 + 1) / 3 * x = (12 + 2) / 3;

5 / 2 * x - 4 / 3 * x = 14 / 3;

(5 * x * 3 - 4 * x * 2) / 6 = 14 / 3;

(15 * x - 12 * x) / 6 = 14 / 3;

3 * x / 6 = 14 / 3;

3 * x / (3 * 2) = 14 / 3;

x / 2 = 14 / 3;

3 * x = 2 * 14;

3 * x = 28;

x = 28 / 3;

Ответ: х = 28 / 3.
