If you divide by x or y it works out

anonymous · Answer

I have to get some sleep, it's almost 2:30. I feel bad leaving you to work on it alone, but I really appreciate it.  I'll be sure to check it tomorrow, so don't feel like you wasted your time.  And if you can't figure it out, thanks for the time and effort. Good night (day)!
