−3x−9=−21

−3x=−21 + 9 (Add 9 to both sides)
−3x=−12
x=−12/−3 (Divide both sides by −3)
x= 4

Answer 2

To complete the solution, we need to determine the value of x.

Given equation: -3x - 9 = -21

Step 1: Add 9 to both sides of the equation:
-3x - 9 + 9 = -21 + 9
-3x = -12

Step 2: Divide both sides of the equation by -3 to isolate x:
(-3x)/(-3) = -12/(-3)
x = 4

Therefore, the completed solution is:
x = 4

Answer 3

To solve the equation −3x−9=−21, we need to isolate the variable x. Let's go step by step:

Step 1: Start with the equation −3x−9=−21.

Step 2: Add 9 to both sides of the equation to eliminate the -9 on the left side:
−3x−9 + 9 = −21 + 9

Simplifying the left side, we get:
−3x = −12

Step 3: To solve for x, divide both sides of the equation by -3:
−3x / -3 = −12 / -3

Simplifying, we have:
x = 4

Therefore, the solution to the equation −3x−9=−21 is x = 4.
