Answer 2

Step-by-step explanation:

let 1/X=m and1/y=n

then eqn

2m+3n=12. ------*2

3m-2n=5. -------*3

then

4m+6n=24

9m-6n=15

adding both eqns

13m=39

m=39/13

===3

then putting value of m in eqn 1

2*3+3n=12

3n=12-6

n=6/3

===2

now

m=3

n=2

then

m=1/X=3

x=1/3

and.

n=1/y=2

y=1/2

then

x=1/3

y=1/2
