Question

Plz give a solution??

Answer 1

Answer:

2/x+3/y=13

5/x-4/y=-2

here, 1/x=p

1/y=q

so, 2p+3q=13 --------1*4

5p-4q=-2. --------2*3

--------------------

8p+12q=52

15p-12q=-6

-------------------------

23p=46

p=46/23

=2

1/x=2

x=1/2

then,

2p+3q=13

2(2)+3q=13

4+3q=13

3q=9

q=3

1/y=3

y=1/3
