2 9/59-a = 1 5/59+16/59=1 21/59
a = 2 9/59 - 1 21/59 = 47/59
3 4/9 - (x - 1 7/9) = 2 2/9
(x - 1 7/9) = 3 4/9 - 2 2/9 = 1 2/9
x = 1 2/9 + 1 7/9 = 3
10 6/10 - (7 3/10- y) = 4 9/10
7 3/10- y = 10 6/10 - 4 9/10 = 5 7/10
y = 7 3/10 - 5 7/10 = 1 6/10
17 18/35 - (n + 4 23/35) = 9 12/35
(n + 4 23/35) = 17 18/35 - 9 12/35 = 8 6/35
n = 8 6/35 - 4 23/35 = 3 18/35
