5.34 Решите уравнение: a) (x - 111) - 59 - 11 918; 6) 975 - (y - 615) - 12675; в) (30 901 - a) : 605-51; r) 39 765 : (b - 893) - 1205.

а) $$ (x - 111) \cdot 59 = 11918 $$

$$ x - 111 = \frac{11918}{59} $$

$$ x - 111 = 202 $$

$$ x = 202 + 111 $$

$$ x = 313 $$

б) $$ 975 - (y - 615) = 12675 $$

$$ -(y - 615) = 12675 - 975 $$

$$ -(y - 615) = 11700 $$

$$ y - 615 = -11700 $$

$$ y = -11700 + 615 $$

$$ y = -11085 $$

в) $$ (30901 - a) : 605 = 51 $$

$$ 30901 - a = 51 \cdot 605 $$

$$ 30901 - a = 30855 $$

$$ a = 30901 - 30855 $$

$$ a = 46 $$

г) $$ 39765 : (b - 893) = 1205 $$

$$ b - 893 = \frac{39765}{1205} $$

$$ b - 893 = 33 $$

$$ b = 33 + 893 $$

$$ b = 926 $$

Ответ: а) $$x = 313$$; б) $$y = -11085$$; в) $$a = 46$$; г) $$b = 926$$
