Answer:

The numbers are 7 and 9.

Explanation:

Let's call the numbers a and b.

We know their difference is 2: a-b=2

We know their sum is 16: a+b=16

Let's take the first expression and isolate a:

a-b=2

a-b+b=2+b

a=2+b

Know let's sub in this value for a into the second expression to find a value for b:

a+b=16

2+b+b=16

2+2b=16

2b=14

b=7

We know a=2+b, and b=7, so a=2+7=9

This means the numbers are 7 and 9.
