you can sum like terms ...

4x, 7x and -5x are all like terms $\implies 4x + 7x - 5x = 11x - 5x = 6x$

for the second, like terms have the same variables to the same power. like terms have the same color in the expression below ...

${\color{red}4x^2} {\color{blue}-2xy} {\color{green}-3y^2}{\color{blue}+6xy}{\color{green}+3y^2}{\color{red}-x^2} $

I assume you know how to sum terms with the same and/or different signs

Why don't you try and combine them ...

have a look at the link, too
