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.
