Answer:
x = 2, y = 1
Step-by-step explanation:
Multiply first equation by 2 and second equation by 3 and subtract.
(6/x+y + 4/x-y) - (6/x+y + 9/x-y) = 6 - 11
- 5/x-y = - 5
x-y = 1 ----------------> Equation 1.
Multiply first equation by 3 and second equation by 2 and subtract.
(9/x+y + 6/x-y) - (4/x+y + 6/x-y) = 9 - 22/3
5/x+y = 5/3
x+ y = 3 ============> equation 2
Add equation 1 and equation 2
x -y = 1
x + y = 3
----------
2x = 4 => x = 2,
----------------------
substitute value of x in equation 1 =>
2 - y = 1 ===> y = 1.
