Question

5/x+y - 2/x-y = -1
15/x+y + 7/x-y = 10

Answer 1

Answer:

x=5/3, y=10/3

Step-by-step explanation:

Answer 2

I think your question is what is the point that satisfies the give equations.

Answer: (3,2)

Step-by-step explanation:

Let,1/(x+y)=a and 1/(x-y)=b

then the two equations will become as follows

5a-2b= - 1  eqn-1

15a+7b=10 eqn-2

by solving two equations

we get b=1,a=1/5

as 1/(x+y)=a and 1/(x-y)=b

we get,

x+y=5

x-y=1

x=3,y=2

∴The point that satisfies the equation is (3,2)
