Question

1/x+1/y=12;3/x-2/y=1

Answer 1

let us take 1/x as p and 1/y as q

acc /question

p + q =12 and 3p -2q =1

acc to elimination method

(p+q=12)2.

(3p -2q=1)1

2p +2q =24

3p-2q==1

5p =25

p=25/5=5

so we got5=p

then 3p -2q=1 substitute the value of p

15-2q =1

-2q=1-15

-2q=-14

q=-14/-2=7now q we get as 7

therefore 1/x=5=x=1/5

1 /y=7y=1/7

hope it will help you
