$q=-1$

Identify and combine like terms:

Like terms are shown by a common color

$color(red)(-8)color(blue)(-12q)=color(red)(-7)color(blue)(-11q)$

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

$color(red)(-8+7)color(blue)(-12q+12q)=color(red)(-7+7)color(blue)(-11q+12q)$

Simplify:

$color(red)(-1)+color(blue)0=color(red)0+color(blue)q$

$-1=q$

How do you solve -8-12q=-7-11q-8-12q=-7-11q?
