Answer 1

To solve the equation \(-3x - 9 = -21\), we follow these steps:

1. Add 9 to both sides to isolate the term with \(x\): \[ -3x - 9 + 9 = -21 + 9 \] This simplifies to: \[ -3x = -12 \]

2. Divide both sides by -3 to solve for \(x\): \[ \frac{-3x}{-3} = \frac{-12}{-3} \] This simplifies to: \[ x = 4 \]

So, the completed solution steps are:

1. Add \(9\) to both sides to obtain \(-3x = -12\).
2. Divide both sides by \(-3\) to get \(x = 4\).

Thus, \(x = 4\) is the solution.
