Решим уравнения:

1) х - 2 = - 3,5;

x = - 3.5 + 2;

x = - 1.5;

2) - 1,5 - х = - 2;

-x = - 2 + 1.5;

-x = - 0.5;

x = - 0.5 / (-1);

x = 0.5/1;

x = 0.5;

3) х - 4/3 = - 7/3;

x = - 7/3 + 4/3;

x = (-7 + 4) / 3;

x = - 3/3;

x = - 1;

4) х + 15/7 = - 13/7;

x = - 13/7 - 15/7;

x = (-13 - 15) / 7;

x = - 28/7;

x = - 4;

5) - х = 3,5 + (-14/3);

-x = 3.5 - 14/3;

-x = 7/2 - 14/3;

-x = (7 * 3 - 14 * 2) / 6;

-x = (21 - 28) / 6;

-x = - 7/6;

x = 7/6;

6) - х = - 7,2 - (-19/3);

-x = - 7.2 + 19/3;

-x = - 7 1/5 + 19/3;

-x = - 36/5 + 19/3;

-x = (-36 * 3 + 19 * 5) / 15;

-x = (-108 + 95) / 15;

-x = - 13/15;

x = 13/15.
