We have the expression 2x + 3y + 2(x - y) - 3x.
And we need to simplify it.
We can start with distributive property. This states that a(b + c) = ab + ac
2x + 3y + 2(x - y) - 3x becomes 2x + 3y + 2x - 2y - 3x
Then combine like terms. This means if we have two terms that have the same variable and exponent, we can combine them. Which is adding or subtracting.
2x + 3y + 2x - 2y - 3x becomes x + y
So, the answer to this question x + y.
