the equation -3x-9=-21 is solved as follows. supply the correct numbers to complete the solution -3x = __ add 9 to both sides x= __ divide both sides by -3

Answer 1

The equation -3x - 9 = -21 can be solved as follows:

-3x = -21 + 9 (add 9 to both sides)
-3x = -12 (simplify)
x = -12 / -3 (divide both sides by -3)

The correct numbers to complete the solution are:

-3x = -12
x = 4
