Решите уравнение: a) 31 * (m + 378) = 17267; б) 202 * (192 + n) = 98980; в) 43966 : (z - 105) = 1157; г) 27384 : (3912 - x) = 7.

а) $$31(m + 378) = 17267$$ $$m + 378 = rac{17267}{31}$$ $$m + 378 = 557$$ $$m = 557 - 378$$ $$m = 179$$ **Ответ: m = 179** б) $$202(192 + n) = 98980$$ $$192 + n = rac{98980}{202}$$ $$192 + n = 490$$ $$n = 490 - 192$$ $$n = 298$$ **Ответ: n = 298** в) $$43966 : (z - 105) = 1157$$ $$z - 105 = rac{43966}{1157}$$ $$z - 105 = 38$$ $$z = 38 + 105$$ $$z = 143$$ **Ответ: z = 143** г) $$27384 : (3912 - x) = 7$$ $$3912 - x = rac{27384}{7}$$ $$3912 - x = 3912$$ $$x = 3912 - 3912$$ $$x = 0$$ **Ответ: x = 0**
