Simplify 2x - 8x - 6y + 9 -14 + x + 11y.

So once you find the like terms your problem will look  like this:
(2x-8x+x)-(6y+11y)+(9-14)
so know you can simply simplify what is in your Parentheses and once that is done it is going to look like this:
(-5x)-(17y)+(-5)
now it looks like that so that would be your answer could you simplified all of the  like terms you can't do anything else to the problem!
So again your answer would look like:
(-5x)-(17y)+(-5)
~Good Luck~
