Answer 2

The two numbers are: 8 and 16.

Explanation:

Let the two unknown numbers be a and b.

The sum of the two number is 24. In other words:

`a+b=24`

The second number is equal to twice the first number. In other words:

`a=2b`

This is a system of equations. Solve by substitution:

`a+b=24\\a=2b\\\\2b+b=24\\3b=24\\b=8\\a=2b\\a=2(8)=16`
