Answer 1

Answer:

Step-by-step explanation:

let 1/x+y be a and 1/x-y be b

then,

6a=7b+3 i.e 6a-7b=3

3a=2b then 6a=4b

4b-7b=3

-3b=3

b=-1

a=2/3b

=2/3[-1]=-2/3

a=1/x+y=-2/3

x+y = -3/2--[1]

1/x-y=b

1/x-y=-1

x-y = -1---[2]

adding [1] & [2]

we get 2x = -3/2 -1

=-5/2

hence x=-5/4

y=1+x

=1 +[-5/4]

=-1/4

pls mark me brainliest.
