hope it helps..

Answer 2

Answer:

let one number be x

and other be y

atq

x/y=7/2

2x-7y=0------(i)

also x+y=18------(ii)

now solving (ii)

x=18-y

put x in (i)

2(18-y)-7y=0

36-2y-7y=0

36-9y=0

-(9y-36)=0

(- sign is cancelled)

9y-36=0

9y=36

y=36÷4

y=9

put y in x

x=18-y

x=9

but this does not satisfy the equation

so your question is wrong
