$q = - 1$

#### Explanation:

Identify and combine like terms:

Like terms are shown by a common color

$\textcolor{red}{- 8} \textcolor{b l u e}{- 12 q} = \textcolor{red}{- 7} \textcolor{b l u e}{- 11 q}$

Let's add $7$ and $12 q$ to both sides

$\textcolor{red}{- 8 + 7} \textcolor{b l u e}{- 12 q + 12 q} = \textcolor{red}{- 7 + 7} \textcolor{b l u e}{- 11 q + 12 q}$

Simplify:

$\textcolor{red}{- 1} + \textcolor{b l u e}{0} = \textcolor{red}{0} + \textcolor{b l u e}{q}$

$- 1 = q$
