Пошаговое объяснение:
x - 2 1/9 = 12 2/3
x = 12 2/3 + 2 1/9
x = 12 6/9 + 2 1/9
x = 14 7/9
------------------------------
x - 6 1/3 = 7 1/4
x = 7 1/4 + 6 1/3
x = 7 3/12 + 6 4/12
x = 13 7/12
-------------------------
x - 13 4/15 = 4 2/5
x = 4 2/5 + 13 4/15
x = 4 6/15 + 13 4/15
x = 17 10/15
x = 17 2/3
----------------------
x - 2 3/5 = 12 1/6
x = 12 1/6 + 2 3/5
x = 12 5/30 + 2 18/30
x = 14 23/30
