if the mean and the median are the same, that means that the middle number and 20+x+y/5 are the same, and because the median has to be a whole number, then 20+x+y/5 has to be a whole number as well, so x+y is a multiple of 5. (from here I guessed because there are limited answers) I got 7as x and 8 as y.

x is the median since it's the middle number and since it's the median, it's also the mean. 

5x will be the sum of all the numbers since it's the mean. 

5x = 20 + x+ y

4x = 20 + y

So, you can plug some numbers in and try them. But, x and y must remain in order so x must be greater or equal to 6, and also less than or equal to y. 

x = 7 

y = 8. 

4(7) = 20 + 8

I hope this helped. :))
