The equation −3x−9=−21 is solved as follows. Enter the correct numbers to complete the solution.(1 point) −3x−9=−21 −3x= Add 9 to both sides of the equation. x= Divide both sides of the equation by -3. If the answer is an improper fraction, enter the improper fraction.

Answer 1

Let's solve the equation step by step and fill in the missing parts correctly.

Starting with the equation:

\[ -3x - 9 = -21 \]

1. Add 9 to both sides of the equation: \[ -3x - 9 + 9 = -21 + 9 \] This simplifies to: \[ -3x = -12 \]

2. Divide both sides of the equation by -3: \[ \frac{-3x}{-3} = \frac{-12}{-3} \] This simplifies to: \[ x = 4 \]

So, to complete the solution in the solution format:

• Initial equation: \(-3x - 9 = -21\)
• After adding 9: \(-3x = -12\)
• After dividing by -3: \(x = 4\)

If you are required to enter the solution as an improper fraction, you can also write \(4\) as \(\frac{4}{1}\) if necessary.
