I can help u but just give me 5 mins or 2 to help u :) ill get back to u right away

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
The answer would be: x+2y
First, combine the like terms.
-x and 2x
Now your equation looks like this:
x+y+y
Now combine the y like terms.
y and y and you get 2y
Then you are left with your answer: x+2y
Hope this helps! :3
