Posted by Joel on Wednesday, August 15, 2007 at 10:33pm.

6xy + 9xy 15xy
------------- = ----------
3xy 3xy
= (15/3) (x/x) (y/y) = 5y

Just want it to know if is correct, but don't y + y = 2y? I'm confused now. Can someone please help?

yes, the answer is 5y and
yes, y + y = 2y
but where did this last part enter the picture?

someone ask me where they came from and he was saying that I was wrong; and now I have my doubts, and it confused me. I thought I had it right. I don't know how to break it down for a better understanding, I had help with the problem. Please help
