5.34 Решите уравнение: a) (x - 111). 59 = 11 918; 6) 975 (y - 615) = 12 675; в) (30 901 a) : 605 = 51; г) 39 765 : (b - 893) = 1205.

a) $$(x - 111) \cdot 59 = 11918$$

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

$$x - 111 = 202$$

$$x = 202 + 111$$

$$x = 313$$

б) $$975 \cdot (y - 615) = 12675$$

$$y - 615 = \frac{12675}{975}$$

$$y - 615 = 13$$

$$y = 13 + 615$$

$$y = 628$$

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: a) 313; б) 628; в) 46; г) 926.
