Answer 3

To simplify the expression $\frac{1}{3}x^2 - \frac{1}{3}y + \frac{2}{3}x^2 + \frac{1}{3}y$, you can combine like terms:

$\frac{1}{3}x^2 + \frac{2}{3}x^2 - \frac{1}{3}y + \frac{1}{3}y$

Now, add the terms with x^2 and y separately:

$\frac{1}{3}x^2 + \frac{2}{3}x^2$ and $-\frac{1}{3}y + \frac{1}{3}y$

$\frac{1}{3}x^2 + \frac{2}{3}x^2 = \frac{3}{3}x^2 = x^2$

$-\frac{1}{3}y + \frac{1}{3}y = 0$

So, the simplified expression is:

$x^2 + 0$ which is simply $x^2$.
