Answer:
3x+y+10
Step-by-step explanation:
Since we are trying to combine like terms, we must rearrange the terms, and group the terms with an x, together, a y together, and the constants. Doing that, we get
(5x+x-3x)+(2y-y)+10
Now we start with the x terms, and we add 5x+x=6x and then 6x-3x= 3x, so you have 3x, and now for the y terms
we have 2y-y=y and lastly we have a ten, so adding them together, we get
3x+y+10
