5 3/5 -(6-1/15х)=(1 3/5х-2/5)
​

Ответ:

х = 0

Пошаговое объяснение:

5 3/5 - (6-1/15х) = (1 3/5х-2/5)

5 3/5 - 6 + 1/15х = 1 3/5х - 2/5

1/15х - 1 3/5х = 6 - 5 3/5 - 2/5

1/15х - 1 9/15х = 0

-1 8/15х = 0

х = 0/(-1 8/15)

х = 0

Проверка:

5 3/5 - (6-1/15*0) = (1 3/5*0-2/5)

5 3/5 - (6 - 0) = 0 - 2/5

5 3/5 - 6 = -2/5

-2/5 = -2/5 - верно
