Answer 1

ur answer is

x=5 and y = 1/7

15/x+2/y=17/1 ; 1/x+1/y=36/5

let us suppose :

1/x=a and 1/y=b

now we get the following equation by substituting the above values

5a+5b=36 and 15a+2b=17

by solving this with substitution method we get

b=7 and a=1/5

if we put this value in 1/x=a and 1/y=b

we get

x=5 and y =1/7
