Решите уравнения. 24-(x2)=21 150(x2)=5 12-(x+2)=24(x+1)

Найдем корешки.

1) 24 - (x/2) = 21; 

x/2 = 24 - 21;

x/2 = 3;

x = 3 * 2;

x = 6.

2) 150/(x * 2) = 5; 

30/(x * 2) = 1;

2 * x = 30;

x  = 30/2;

x = 5.

3) 12 - (x + 2) = 24 * (x + 1);   

12 - x - 2 = 24 * x + 24; 

10 - x = 24 * x + 24; 

-x - 24 * x = 24 - 10; 

-25 * x = 14; 

x = -14/25.
