Question

-3x-9=-21
Enter the correct numbers to complete the solution.

Answer 1

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

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

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

So, the solution is \(x = 4\).
If you need specific numbers filled in, they would be:
- The first step result is \(-3x = -12\).
- The final answer is \(x = 4\).
