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

Приравняем все уравнения к -8.

1. 3х = -8;

х = -8 : 3;

х = -2 2/3.

2. - 121/6х = -8;

-8 * 6х = -121;

48х = 121;

х = 121/48;

х = 2 25/48.

3. -2/3 - 5х = -8;

-5х = -8 + 2/3;

5х = 8 - 2/3;

5х = 7 1/3;

х = 22/3 : 5;

х = 22/15;

х = 1 7/15.

4. 4 - 3/4х = -8;

-3/4х = -8 - 4;

-3/4х = -12;

3/4х = 12;

х = (12 * 4) : 3;

х = 16.

5. -97х = -8;

97х = 8;

х = 8/97.

6. - 1,42 / 3х = -8;

- 1,42 = -24х;

24х = 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.
