Решите уравнение 1) 21 (18+x) = 714 2) 16 (4x-34) = 608 3) 12 (152+19x) = 2052 4) (152x+32) * 6=192

Найдем корни.

1) 21 * (18 + x) = 714;

18 + x = 714/21;

x + 18 = 34;

x = 34 - 18;

x = 16.

2) 16 * (4 * x - 34) = 608;

4 * x - 34 = 608/16;

4 * x - 34 = 38;

4 * x = 38 + 34;

4 * x = 72;

2 * x = 36;

x = 36/2;

x = 18.

3) 12 * (152 + 19 * x) = 2 052;

152 + 19 * x = 2 052/12;

19 * x + 152 = 171;

19 * x = 171 - 152;

19 * x = 19;

x = 19/19;

x = 1.

4) (152 * x + 32) * 6 = 192;

152 * x + 32 = 192/6;

152 * x + 32 = 32;

152 * x = 32 - 32;

152 * x = 0;

x = 0/152;

x = 0.
