Решите уравнения-4 х+5+х=-7-2 х+93 х-6=2+5 х-112-7 х+2=32 х+3+7 х=0

Найдем корень.

1) - 4 * х + 5 + х = - 7 - 2 * х + 9;

-3 * x + 5 = - 2 * x + 2;

-3 * x + 2 * x = 2 - 5;

-x = - 3;

x = 3.

2) 3 * х - 6 = 2 + 5 * х - 1;

3 * x - 6 = 5 * x + 1;

3 * x - 5 * x = 1 + 6;

-2 * x = 7;

x = - 7/2;

x = - 3.5.

3) 12 - 7 * х + 2 = 3;

-7 * x + 14 = 3;

-7 * x = 3 - 14;

-7 * x = - 11;

x = 11/7.

4) 2 * х + 3 + 7 * х = 0;

9 * x + 3 = 0;

9 * x = - 3;

x = - 3/9;

x = - 1/3.
