Answer:
x+10
Explanation:
You must combine like terms (x) and (y).
4x-3x and 8y+2y
x+10y
When you simplify, you use the signs in front of the like terms to find if you subtract or not.
4x + 8y -3x +2y
As you can see, the 4x is positive b/c there's not a sign in front and then the 3x is -3x b/c there is a subtraction in front of it.
With the (y) values, it is addition in front of the 8 so it is 8y. There is an addition side in front of the 2y as well so it is also positive so you add.
Hope it helps!
