3(2,4-1,1m)=2,7m+3,2

Решим уравнение.3 * (2,4 - 1,1m) = 2,7m + 3,2;7,2 - 3,3m = 2,7m + 3,2;-3,3m - 2,7m = 3,2 - 7,2;-6m = -4;m = -4 : (-6);m = 2/3.Ответ: m = 2/3.Сделаем проверку.3 * (24/10 - 11/10 * 2/3) = 27/10 * 2/3 + 32/10;3 * (24/10 - 11/15) = 9/5 + 32/10;3 * (72 - 22)/30 = (18 + 32)/10;3 * 50/30 = 50/10;50/10 = 50/10;5 = 5, верно.
