Answer:
4y
Explanation:
To simplify the expression 2x + 4y - 2x, we can combine like terms.
The terms 2x and -2x are like terms because they have the same variable, x, raised to the same power, which is 1. When we subtract 2x from 2x, we get 0x, which simplifies to 0.
So, the expression simplifies to 4y + 0, which is just 4y.
Therefore, the simplified form of 2x + 4y - 2x is 4y.
