$\frac{-2n-2}{12} = 12 \\ \\ \frac{-2(n + 1)}{12} = 12 \ / \ factor \ out \ 2 \\ \\ - \frac{n+1}{6} = 12 \ / \ simplify \\ \\ -n - 1 = 12 \times 6 \ / \ multiply \ each \ side \ by \ 6 \\ \\ -n - 1 = 72 \ / \ simplify \\ \\ -n = 72 + 1 \ / \ add \ 1 \ to \ each \ side \\ \\ -n = 73 \ / \ simplify \\ \\ n = -73 \ / \ multiply \ each \ side \ by \ -1 \\ \\$

So, your answer to this problem is n = -73.
