3 х=-121/6 х=-2/3-5x=4-3/4x=-97x=-1,42/3x=-8

Приравняем все уравнения к - 8.

1. 3 х = - 8;

х = - 8 : 3;

х = - 2 2/3.

2. - 121/6 х = - 8;

-8 * 6 х = - 121;

48 х = 121;

х = 121/48;

х = 2 25/48.

3. - 2/3 - 5 х = - 8;

-5 х = - 8 + 2/3;

5 х = 8 - 2/3;

5 х = 7 1/3;

х = 22/3 : 5;

х = 22/15;

х = 1 7/15.

4. 4 - 3/4 х = - 8;

-3/4 х = - 8 - 4;

-3/4 х = - 12;

3/4 х = 12;

х = (12 * 4) : 3;

х = 16.

5. - 97 х = - 8;

97 х = 8;

х = 8/97.

6. - 1,42 / 3 х = - 8;

- 1,42 = - 24 х;

24 х = 1,42;

х = (142/100) : 24;

х = 142/2400 = 71/1200.

Ответ: х1 = - 2 2/3; х2 = 2 25/48; х3 = 1 7/15; х4 = 16; х5 = 8/97; х6 = 71/1200.
