Имеем 3 склада. Считаем сколько всего груза 400+300+440=1140 Каждый склад упоминается по 2 раза (1+2, 2+3, 3+1) , поэтому 1440 делим на 2 = 570. Известно . что на первый и второй склады доставили 400 тонн, значит на третий доставили 570-400=170тонн Известно, что на первый и третий склады доставили 440 тонн, значит на второй доставили 570-440=130 тонн Известно, что на второй и третий склады доставили 300 тонн, значит на первый доставили 570-300=270 тонн Проверка 1+2=400 т следовательно 270+130=400 2+3=300 т следовательно 130+170= 300 1+3=440 т следовательно 270+170=440 ответ: 1=270 тонн 2=130 тонн 3=170 тонн
10007*2-в=10000, 10014-в=10000, -в=10000-10014=-14, в=14
