9,6,3, and 7

Explanation:

This question is considered "guess and check". You would have to take a guess at what the answer is and then double check it. There is no formula to solve it in one go.

To begin, we want to try to think of some numbers that we could add together to equal about 1/2 of 25 or something close to half. At this point, I tried to get 15 and 10 so that I could add them together and get 25.

I began by adding 9 and 6 together and got 15. After this, I added 3 and 7 together to get 10 since we already used 6 and couldn't use 5.

This gives you the answer of 25.

I hope this helped!
