SOLVE TWO-STEP EQUATIONS PRACTICE NEED HELP
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.
To solve the equation -3x - 9 = -21, we can follow these steps:
Step 1: Add 9 to both sides to isolate the variable term.
-3x - 9 + 9 = -21 + 9
-3x = -12
Step 2: Divide both sides by -3 to solve for x.
(-3x) / -3 = (-12) / -3
x = 4
Therefore, the solution to the equation -3x - 9 = -21 is x = 4.
To solve the equation -3X - 9 = -21, we need to isolate the variable X by performing the necessary steps. Here's a step-by-step solution:
Step 1: Simplify the equation.
-3X - 9 = -21
Remove the parentheses:
-3X - 9 = -21
Step 2: Move the constant term to the right side of the equation.
-3X = -21 + 9
Simplify the right side:
-3X = -12
Step 3: Divide both sides of the equation by the coefficient of X (-3).
-3X / -3 = -12 / -3
Simplify both sides:
X = 4
Therefore, the solution to the equation -3X - 9 = -21 is X = 4.
