Решить уравнение 835-2 х=97; 486-7x=297; x+59=181; 483+x=765; x-115=252; x-397=196; 931-x=94; 585-x=268

Найдем корень.

1) 835 - 2 * х = 97;

-2 * x = 97 - 835;

-2 * x = - 738;

2 * x = 738;

x = 738/2;

x = 369.

2) 486 - 7 * x = 297;

-7 * x = 297 - 486;

-7 * x = - 189;

x = 189/7;

x = 27.

3) x + 59 = 181;

x = 181 - 59;

x = 122.

4) 483 + x = 765;

x = 765 - 483;

x = 22;

5) x - 115 = 252;

x = 252 + 115;

x = 367.

6) x - 397 = 196;

x = 397 + 196;

x = 593.

7) 931 - x = 94;

-x = 94 - 931;

-x = - 837;

x = 837.

8) 585 - x = 268;

-x = 268 - 585;

-x = - 317;

x = 317.
