To solve the equation \(-90 = -6a - 12\), we can follow these steps:
1. **Add 12 to both sides** to isolate the term with \(a\):
\[
-90 + 12 = -6a
\]
This simplifies to:
\[
-78 = -6a
\]
2. **Divide both sides by -6** to solve for \(a\):
\[
a = \frac{-78}{-6}
\]
Simplifying the right side gives:
\[
a = 13
\]
Therefore, the solution is:
\[
a = 13
\]
