Решите уравнения: 11х = 36- х 9х + 4 = 48

1) 11х = 36 - х;

11х + х = 36;

12х = 36;

х = 36 : 12;

х = 3.

2) 9х + 4 = 48 - 2х;

9х + 2х = 48 - 4;

11х = 44;

х = 44 : 11;

х = 4.

3) 8 - 4х = 2х - 16;

8 + 16 = 2х + 4х;

24 = 6х;

х = 24 : 6;

х = 4.

4) 0,4х + 3,8 = -0,8х + 2,6;

0,4х + 0,8х = 2,6 - 3,8;

1,2х = -1,2;

х = -1,2 : 1,2;

х = -1.

5) 6,8 - 1,3х = 0,6х - 2,7;

-1,3х - 0,6х = -2,7 - 6,8;

-1,9х = -9,5;

х = -9,5 : (-1,9);

х = 5.

6) 4/9х + 14 = 1/6х + 9;

4/9х - 1/6х = 9 - 14;

(4 * 2)/(9 * 2)х - (1 * 3)/(6 * 3)х = -5;

8/18х - 3/18х = -5;

5/18х = -5;

х = -5 : 5/18;

х = -5 * 18/5;

х = -18.
