The sum of these two numbers is 25, ad 17 and 8 have a difference of 9

Explanation:

Answer 2

8 and 17

Explanation:

Let the number x and y

Sum of numbers, x + y = 25 -----------( 1 )

One number exceeds other by 9,

that is difference between the numbers is 9, x - y = 9

=> x = 9 + y --------- ( 2 )

Substitute ( 2 ) in ( 1 )

( 9 + y ) + y = 25

2y = 25 - 9

2y = 16

y = 8

Substitute y = 8 in ( 2 ) : x = 9 + y

= 9 + 8 = 17

Therefore the 2 numbers are 8 and 17
