The equation −3x−9=−21 is solved as follows. Supply the correct numbers to complete the solution.(1 point) −3x−9=−21 −3x= Add 9 to both sides. x= Divide both sides by −3.

Answer 1

To complete the solution, we can use the following steps:

−3x − 9 = −21
−3x = −21 + 9 (Adding 9 to both sides)
−3x = -12 (Simplifying the right side)
x = -12 ÷ -3 (Dividing both sides by -3)
x = 4 (Simplifying the right side)

Therefore, the correct numbers to complete the solution are 9 and -3.
