Решите уравнение: - 5 (-1+9 х) - 5 х=-1 - 6 (1-х) + 4 х=-4 - 8 (3+х) + х=4

Вычислим корни уравнений:

1) - 5 * (-1 + 9 * х) - 5 * х = - 1;

-5 * (-1) - 5 * 9 * x - 5 * x = - 1;

5 - 45 * x - 5 * x = - 1;

5 - x * (45 + 5) = - 1;

5 - 50 * x = - 1;

-50 * x = - 1 - 5;

-50 * x = - 6;

50 * x = 6;

x = 6/50;

x = 3/25.

2) - 6 * (1 - х) + 4 * х = - 4;

-6 + 6 * x + 4 * x = - 4;

-6 + 10 * x = - 4;

10 x = - 4 + 6;

10 * x = 2;

x = 2/10;

x = 1/2.

3) - 8 * (3 + х) + х = 4;

-8 * 3 - 8 * x + x = 4;

-24 - 8 * x + x = 4;

-24 - 7 * x = 4;

-7 * x = 4 + 24;

-7 * x = 28;

x = - 28/7;

x = - 4.
