Combine like terms.You can rewrite them so that the terms are together but be careful of the signs.
9 – 3x -(-8y) + 9x + y….
9 – 3x + 9x – (-8y) + y..
9 + 6x + 9y
Now you try it!!!

I will do one and explain it as I go try to do the others on your own. First group th letters together like this:
9-3x-(-8y)+9x+y turns into 9x-3x+9+y-(-8y)
then get the() out by saying a minus a neg. is like plus a pos.
so then your prob. looks like:
9x-3x+9+y+8y
then you add like letters together and get:
6x+9+9y
