Решите уравнение ( - 3,1) * x + 2,6 * x - 0,7 * x = - 2,7

( - 3, 1) * x + 2, 6 * x - 0, 7 * x = - 2, 7;

- 3, 1 * x + 2, 6 * x - 0, 7 * x = - 2, 7;

x * ( - 3. 1 + 2. 6 - 0. 7) = - 2, 7;

x * ( - 3 - 0. 1 + 2 + 0. 6 - 0. 7) = - 2, 7;

x * ( - 1 - 0. 1 - 0. 1) = - 2, 7;

x * ( - 1 - 0. 2) = - 2, 7;

- 1. 2 * x = - 2. 7;

1. 2 * x = 2. 7;

1 целая 2 / 10 * x = 2 целых 7 / 10;

(1 * 10 + 2) / 10 * х = (2 * 10 + 7) / 10;

(20 + 2) / 10 * х = (40 + 7) / 10;

22 / 10 * х = 47 / 10;

x = 47 / 10 / (22 / 10);

x = 47 / 10 * (10 / 22);

x = 47 / 22.
