Assume the problems is:
%28%28x-y%29%29%2F%28%28x%2By%29%29 = 4%2F5
:
From this we can say:
x - y = 4
x + y = 5
---------------adding eliminates y, find x
2x = 9
x = 9%2F2
x = 4.5
:
Find y using x + y = 5
4.5 + y = 5
y = 5 - 4.5
y = .5
:
Check solution in original equation:
%28%284.5-.5%29%29%2F%28%284.5%2B.5%29%29 = 4%2F5
4%2F5 = 4%2F5
