Решите уравнения 3 х+5 х+96=1568 357z-149z--1843=11469 2 у+7 у+78=1581

Найдем корни.

1) 3 * х + 5 * х + 96 = 1 568;

x * (3 + 5) + 96 = 1 568;

8 * x + 96 = 1 568;

8 * x = 1 568 - 96;

8 * x = 1 472;

x = 1 472/8;

x = 184.

2) 357 * z - 149 * z - 1 843 = 11 469;

357 * z - 149 * z = 11 469 + 1 843;

357 * z - 149 * z = 13 312;

208 * z = 13 312;

z = 13 312/208;

z = 64.

3) 2 * у + 7 * у + 78 = 1 581;

9 * y + 78 = 1 581;

9 * y = 1 581 - 78;

9 * y = 1 503;

y = 1 503/9;

y = 167.
