To complete the solution, we add 9 to both sides of the equation:
−3x − 9 + 9 = −21 + 9
−3x = -12
Next, we need to divide both sides of the equation by -3 to isolate x:
x = -12 / -3
Simplifying the expression on the right side, we get:
x = 4
So, the solution to the equation is x = 4.
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
