Пошаговое объяснение:

(1 1/6 + 7,3у)/3 = (0,6у + 1 5/15)/2

2 * (1 1/6 + 7,3y) = 3 * (0,6y + 1 5/15)

2 * (7/6 + 7,3y) = 3 * (0,6y + 20/15)

14/6 + 14,6y = 1,8y + 60/15

2 2/6 + 14,6y = 1,8y + 4

14,6y - 1,8y = 4 - 2 2/6

12,8y = 3 6/6 - 2 2/6

12,8y = 1 4/6

y = 1 4/6 : 12,8

y = 10/6 : 128/10

y = = 10/6 * 10/128

y = 5/3 * 5/64

y = 25/192
