Пошаговое объяснение:

x + 2 2/11 = 5

x = 5 - 2 2/11

x = 4 11/11 - 2 2/11

x = 2 9/11

------------

26 5/8 + a = 30

a = 30 - 26 5/8

a = 29 8/8 - 26 5/8

a = 3 3/8

----------

n - 6 5/6 = 2/9

n = 2/9 + 6 5/6

n = 4/18 + 6 15/18

n = 6 19/18

n = 7 1/18

-----------

11 1/4 - x = 3 7/10

x = 11 1/4 - 3 7/10

x = 11 5/20 - 3 14/20

x = 10 25/20 - 3 14/20

x = 7 11/20

-------------

3 11/24 - x = 1 1/6 + 1 1/9

3 11/24 - x = 1 3/18 + 1 2/18

3 11/24 - x = 2 5/18

x = 3 11/24 - 2 5/18

x = 3 33/72 - 2 20/72

x = 1 13/72

-----------------

y + 5/7 = 1/8 + 2/3 - 1/14

y + 5/7 = 21/168 + 112/168 - 12/168

y + 5/7 = 121/168

y = 121/168 - 5/7

y = 121/168 - 120/168

y = 1/168
