$= 9 x + 9$ $=9x+9$

Explanation:

We can add everything together. The variables for themselves and the integers for themselves.

$3 x + 1 x + 2 - (- 5 x) + 7$ $3x+1x+2-(-5x)+7$

$4 x + 2 - (- 5 x) + 7$ $4x+2-(-5x)+7$

For $- (- 5 x)$ $-(-5x)$ you know that $(-) \cdot (-) = +$ $(-)*(-)=+$ . So, since it's written as $- (- 5 x)$ $-(-5x)$ it will be equal to $5 x$ $5x$ .

$4 x + 2 + 7 - (- 5 x)$ $4x+2+7-(-5x)$

$4 x + 9 + 5 x$ $4x+9+5x$

We will then land on the answer,

$= 9 x + 9$ $=9x+9$
