Question

Solve 20/x−y+ 22/x+y=5 and 10/x-y=33/x+y =8

Answer 1

Given :

20÷×-y + 22÷x+y =5

10÷x-y + 33÷x+y =8​

To find :  Solve for x & y

Solution:

1÷×-y  = u

1÷x+y =v

=> 20u + 22v =  5

    10u  + 33v  = 8   => 20u + 66v  = 16

=> 44v = 11

=> v = 1/4

=> x +  y = 4

u = -1/40

=> x - y = -40

x - y = -40

x +  y = 4

=> x  = -18  ,   y  = 22
