Answer:

the second number is 17 and the first one is 22

Explanation:

We will name x to the second number.

Therefore, if the first number is 5 more than the second number, it would be x + 5.

On the other hand we know that these two numbers sum up 39. So we can write the next equation and solve for x.

$x+x+5=39\\2x=39-5\\2x=34\\x=34/2\\x=17$

Therefore, the second number is 17 and the first one is 22
