3+х=5/9

и

6 1/12-х=2 5/12

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 = 5/9

6 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
