Answer 1

To solve the equation \(-2x - 5 = -21\), here are the best two steps:

Step 1: Add 5 to both sides of the equation.

\(-2x - 5 + 5 = -21 + 5\)

This simplifies to:

\(-2x = -16\)

Step 2: Divide both sides by -2.

\(\frac{-2x}{-2} = \frac{-16}{-2}\)

This simplifies to:

\(x = 8\)

Solution: \(x = 8\)
