Question

Solve the equations

32/x-y + 36/x+y. = 7
40/x-y + 48/x+y =9
pls explain properly in an understandable way​

Answer 1

Step-by-step explanation:

take take 1/x -y =p

and 1/×+y=q

Now,

32p+36q=7..............eq(1)

40p+48q=9..............eq(2)

solving equation 1 and 2

we get

p=1/8

and q=1/12

Now,p=1/x-y

so 1/8=1/x-y.............eq(3)

and q=1/x+y

1/12=1/x+y........…....eq(4)

now solving equation 3 and 4
