To solve the equation \(-2x - 5 = -21\), the best two steps to follow would be:
1. **Add 5 to both sides of the equation** to isolate the term containing \(x\):
\[
-2x - 5 + 5 = -21 + 5 \quad \Rightarrow \quad -2x = -16
\]
2. **Divide both sides by -2** to solve for \(x\):
\[
\frac{-2x}{-2} = \frac{-16}{-2} \quad \Rightarrow \quad x = 8
\]
Thus, the two best steps to solve the equation are to first add 5 to both sides, followed by dividing both sides by -2.
