Answer 2

The two numbers are '9' and '18'.

Explanation:

Let the both numbers be x and y respectively.

The difference between both the number is 9.

x - y = 9..[1]

The sum of both numbers is 27.

x + y = 27..[2]

`x - y = 9`

`x = 9 + y`

Putting value of x from [1] into [2]:

`9 + y + y = 27`

`2 y = 18`

`y=(18)/(2)=9`

`x=9+y=9+9=18`

The two numbers are '9' and '18'.
