Question

СРОЧНО ДАЮ 20 БАЛЛОВ

Answer 1

8 6/7 - x = 4 2/7

x = 8 6/7 - 4 2/7

x = 4 4/7

y - 2 1/5 = 5 2/5

y = 2 1/5 + 5 2/5

y = 7 3/5

y + 5 8/13 = 9 7/13

y = 9 7/13 - 5 8/13

y = 3 12/13

x - 3 5/8 = 1 3/8

x = 3 5/8 + 1 3/8

x = 5

(7 4/12 + y) - 8 5/12 = 6 1/12

7 4/12 + y = 6 1/12 + 8 5/12

7 4/12 + y = 14 6/12

y = 14 6/12 - 7 4/12

y = 7 1/6

(12 5/13 + y) - 9 9/13 = 7 7/13

12 5/13 + y = 7 7/13 + 9 9/13

12 5/13 + y = 17 3/13

y = 17 3/13 - 12 5/13

y = 4 8/13
