3 + х = 5/9,х = 5/9 - 3,х = 5/9 - 27/9,х = - 22/9,х = -2 4/9,проверка:3 + (- 2 4/9) = 5/9,3 - 2 4/9 = 5/9,5/9 = 5/96 1/12 - х = 2 5/12,х = 6 1/12 - 2 5/12,х = 5 13/12 - 2 5/12,х = (5 - 2) + (13/12 - 5/12),х = 3 + 8/12,х = 3 2/3,проверка:6 1/12 - 3 2/3 = 2 5/12,5 13/12 - 3 2/3 = 2 5/12,(5 - 3) + (13/12 - 8/12) = 2 5/12,2 + 5/12 = 2 5/12,2 5/12 = 2 5/12
