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