To solve the equation -3x - 9 = -21, we need to isolate the variable x.
Step 1: Move the constant term to the other side of the equation.
To do this, add 9 to both sides:
-3x - 9 + 9 = -21 + 9
-3x = -12
Step 2: Divide both sides of the equation by -3 to solve for x.
Dividing both sides by -3, we get:
(-3x)/-3 = -12/-3
x = 4
Therefore, the solution to the equation -3x - 9 = -21 is x = 4.
The equation negative 3X -9 equals -21 is solved as follows supply the correct numbers to complete the solution
