We are asked to find the sum of the following expressions

$(-6x+6)\: \: and\: \: (-3x-7)$

First of all, expand the parenthesis

$\begin{gathered} (-6x+6)+\: (-3x-7) \\ -6x+6-3x-7 \end{gathered}$

Now, collect the like terms together and add/subtract

$\begin{gathered} -6x+6-3x-7 \\ (-6x-3x)+(6-7) \\ (-9x)+(-1)_{} \\ -9x-1 \end{gathered}$

Therefore, the sum of the given expressions in the simplest form is
