вот а дальше не знаю извени

Answer 2

1.

1 - y = (2/15)

y = 1 - (2/15)

y = (13/15)

2.

3 (2/7) + x = 7

x = 7 - 3 (2/7)

x = 3 (5/7)

3.

6 (2/5) - x = 4 (3/5)

x = 6 (2/5) - 4 (3/5)

x = 1 (4/5)

4.

x - 3 (8/9) = 4 (6/9)

x = 4 (6/9) + 3 (8/9)

x = 8 (5/9)

5.

7 (4/11) - x = 2 (6/11)

x = 7 (4/11) - 2 (6/11)

x = 4 (9/11)

6.

5 - x = 3 (4/9)

x = 5 - 3 (4/9)

x = 2 (5/9)

7.

8 (5/9) - x = 2 (7/9)

x = 8 (5/9) - 2 (7/9)

x = 5 (7/9)
