Answer 2

Answer:

a. 9 is the answer

Let the two numbers be x and y.

the sum of them is 9.

Thus, x+y=9.................(1)

We know that one number is 9. Let x be 9.

Then, substitute the value of x in (1).

9+y=9.

Transpose 9 to the RHS.

y=9-9

y=0.

Thus, x=9, y=0.

Difference between the two numbers: The difference between x and y.

x-y⇒9-0⇒9.

Thus, x-y=9, The difference between the two numbers is 9.
