We need to solve the equation -3x - 9 = -21.
First, let's isolate the variable by moving the constant term to the other side of the equation.
-3x - 9 + 9 = -21 + 9
Simplifying, we have:
-3x = -12
To solve for x, we divide both sides of the equation by -3:
(-3x) / -3 = (-12) / -3
The negative signs on both sides cancel out, giving us:
x = 4
So the solution to the equation -3x - 9 = -21 is x = 4.
The equation -3x-9=-21 is solved as follows. Supply the correct numbers to complete the solution.
