$\textcolor{p u r p \le}{\text{n = - 3}}$

Explanation:

$\textcolor{m a \ge n t a}{\text{Subtract 12 on both sides:}}$

$\cancel{12} - 12 n = 48$
$\cancel{-} 12$ $\textcolor{w h i t e}{a a a a} - 12$

12 cancels out on the left side, and when you subtract 12 from 48 on the right you get 36:

$- 12 n = 36$

$\textcolor{g r e e b}{\text{Divide both sides by -12 to get n by itself.}}$

(cancel"-12"n)/cancel"-12"=(36)/-12

Now you are just left with $n$ on the left side and -3 on the right side.

Therefore,
$\textcolor{p u r p \le}{\text{n = -3}}$
