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
To complete the solution, we need to follow the steps given in the equation:
−3x−9=−21
1. Add 9 to both sides:
−3x = -21 + 9
−3x = -12
2. Divide both sides by -3 to solve for x:
x = -12 / -3
x = 4
So, the correct numbers to complete the solution are:
−3x = -12
x = 4
fill in the blank space please
−3x = -12. Add 9 to both sides.
−3x + 9 = -12 + 9. Simplify.
−3x + 9 = -3. Subtract 9 from both sides.
−3x = -3 - 9. Simplify.
−3x = -12. Divide both sides by -3.
x = -12 / -3. Simplify.
x = 4.
To complete the solution of the equation −3x − 9 = −21, we will follow these steps:
Step 1: Add 9 to both sides of the equation.
−3x − 9 + 9 = −21 + 9
This simplifies to:
−3x = −12
In this step, we added 9 to both sides of the equation to isolate the term with x.
Step 2: To find the value of x, we need to isolate it. Since the coefficient of x is −3, we can divide both sides of the equation by −3.
(−3x) / (−3) = (−12) / (−3)
This simplifies to:
x = 4
In this step, we divided both sides of the equation by −3 to solve for x.
Therefore, the completed solution involves the following numbers:
−3x = −12
x = 4
