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

a) $$m + 378 = 17267 / 31 = 557 ightarrow m = 557 - 378 = 179$$.

б) $$192 + n = 98980 / 202 = 490 ightarrow n = 490 - 192 = 298$$.

в) $$z - 105 = 43966 / 1157 = 38 ightarrow z = 38 + 105 = 143$$.

г) $$3912 - x = 27384 / 7 = 3912 ightarrow x = 3912 - 3912 = 0$$.
