To solve the equation \(-6 - 2t - 8t = -9t + 1\), we can follow these steps:
-
Combine like terms on the left side:
\[ -6 - 10t = -9t + 1 \]
-
Isolate the variable \(t\). To do this, add \(9t\) to both sides:
\[ -10t + 9t = 1 + 6 \]
This simplifies to:
\[ -t = 7 \]
-
Multiply both sides by -1 to solve for \(t\):
\[ t = -7 \]
So the solution is:
\[ \boxed{-7} \]
