See below...

#### Explanation:

Here we must collect the like terms. By like terms, we mean they are either a constant or they have the same variable

e.g: $x + x = 2 x$

Let's group the like terms.
$7 x + 3 y - 2 + 6 x - 1 + {y}^{2}$

$7 x + 6 x - 2 - 1 + 3 y + {y}^{2}$

And now simplify

$13 x - 3 + 3 y + {y}^{2}$
