Okay, this isn't really a big question. I know how to do it, there's just one thing I have to make sure of.
The problem is:
5x+4y11x2y
I know I need to combine like terms, but which sign do I use to do that.
Like if I want to combine 5x and 11x, do I use the sign before the 11x () of the sign after 5x (+) ????

Use the sign of the larger.
5x+4y11x2y
6x+2y 
Ok. Thank you again! :D
