Решите уравнение 1) 8 7/9 - х = 3 5/6 2) (х - 5/6) + 11/18 = 19/24

1) 8 7/9 - х = 3 5/6 х = 8 7/9 - 3 5/6 х = 8 14/18 - 3 15/18 х = 7 32/18 - 3 15/18 х = 4 17/18 - - - - - - - проверка: 8 14/18 - 4 17/18 = 7 32/18 - 4 17/18 = 3 15/18 = 3 5/6 2) (х - 5/6) + 11/18 = 19/24 х - 5/6 = 19/24 - 11/18 х - 5/6 = 57/72 - 44/72 х - 5/6 = 13/72 х = 13/72 + 5/6 х = 13/72 + 60/72 х = 73/72 х = 1 целая 1/72 - - - - - - - проверка: (73/72 - 60/72) + 44/72 = 57/72 = 19/24

1)х=8 7/9-3 5/6 х=8 14/18 -3 15/18 х=7 32/18-3 15/18 х=4 17/18
