Реши уравнения: 8 (-y-2) = -5y - (6-9y) - b - (b/4+3/8) = 1/2 + (-3b/8-0.5)

8 (-y - 2) = - 5y - (6 - 9y);

-8 у - 16 = - 5 у - 6 + 9 у;

-8 у + 5 у - 9 у = - 6 + 16;

-12 у = 10;

у = 10 : (-12);

у = - 10/12;

у = - 5/6.

Ответ: - 5/6.

-b - (b/4 + 3/8) = 1/2 + (-3b/8 - 0.5);

-b - b/4 - 3/8 = 1/2 - 3b/8 - 1/2;

-b - b/4 + 3b/8 = 1/2 - 1/2 + 3/8;

(-8b - 2b + 3b) / 8 = 3/8;

-7b/8 = 3/8;

-7b * 8 = 3 * 8;

-7b = 3;

b = - 3/7.

Ответ: - 3/7.
