Решительно уравнение 4х+9.3=0,5-15,2 2/7х-1/2=3/4+5/14х х-8/5=3,2-х/4

Решим уравнения.

1) 4 * х + 9.3 = 0,5 - 15,2; 

4 * x = 0.5 - 15.2 - 9.3; 

4 * x = -14.7 - 9.3;

4 * x = -15 - 9;

4 * x = -24; 

x = -24/4; 

x = -6. 

2) 2/7 * х - 1/2 = 3/4 + 5/14 * х; 

2/7 * x - 5/14 * x = 3/4 + 1/2;

4/14 * x - 5/14 * x = 3/4 + 2/4;

-1/14 * x = 6/4;

-1/14 * x = 3/2;

-1/7 * x = 3/1;

-x = 3 * 7;

x = -21.

3) (х - 8)/5 = (3,2 - х)/4; 

4 * (x - 8) = 5 * (3.2 - x); 

4 * x - 32 = 16 - 5 * x; 

4 * x + 5 * x = 16 + 32; 

9 * x = 48; 

x = 48/9.
