Ответ:
(x+22/25)x1/3=-22/3
x/3+22/75=-550/75
x/3=-572/75
x=-572/25=22 22/25
Пошаговое объяснение:
(x+22/25)•1/3=7 1/3
x+22/25=22/3:1/3
x+22/25=22/3•3/1
x+22/25=22
x=22-22/25
x=21 25/25-22/25
x=21 3/25
проверка:
(21 3/25+22/25)•1/3=7 1/3
21 25/25•1/3=7 1/3
22•1/3=7 1/3
22/3=7 1/3
7 1/3=7 1/3 - верно
