Answer:6 and 5

Step-by-step explanation:4 positive whole numbers add up to 39. That means there are 4 factors. One is a multiple of 7. (7,14,21,28,35) The other 3 are equal. Let X equal the multiple of 7, and let Y equal the numbers that are equal.

39=x+3y

Now, we have to fill in the possible multiples of 7.

39=7+3y

39-7=7-7+3y

32=3y

32/3=3y/3

10&2/3=y

When we use 7, the 3 numbers are not equal whole numbers. Let’s try the next multiple.

39=14+3y

39-14=14-14+3y

25/3=3y/3

5=y

Yes, that is a whole positive number. It’s correct.

We have to plug in the other multiples just to check, but I’ll leave out the work.

39=21+3y

6=y

Yes, that is a possible answer.

39=28+3y

3&2/3=y The 3 numbers are not whole numbers.

39=35+3y

1&1/3=y The 3 numbers are not whole numbers.

In conclusion, the TWO possible answers are 39=14+3(5) and 39=21+3(6). If we multiply all four numbers for the first one then it equals 1750, and the second one equals 4536. Not sure what exactly your looking for, but I answered the best I could! Hope this helped. ðŸ™‚
