Question Solve the equation $-3x - 9 = -21$ by filling in the missing numbers.

Studdy Solution

STEP 1

Assumptions1. The given equation is $-3x -9 = -21$ . We need to solve for $x$
3. We can use the properties of equality to solve the equation

STEP 2

First, we need to isolate the term with $x$ on one side of the equation. We can do this by adding9 to both sides of the equation.
$-x -9 +9 = -21 +9$

STEP 3

implify the equation.
$-3x = -21 +9$

STEP 4

Calculate the right side of the equation.
$-3x = -12$ So, the first square in the solution should be filled with $-12$ .

STEP 5

Next, we need to solve for $x$ . We can do this by dividing both sides of the equation by $-3$ .
$x = \frac{-12}{-3}$

STEP 6

Calculate the value of $x$ .
$x =4$ So, the second square in the solution should be filled with $4$ .
The solution to the equation $-3x -9 = -21$ is $x =4$ .

Question Solve the equation −3x−9=−21-3x - 9 = -21−3x−9=−21 by filling in the missing numbers.

Studdy Solution

STEP 1

Assumptions1. The given equation is −3x−9=−21-3x -9 = -21−3x−9=−21 . We need to solve for xxx3. We can use the properties of equality to solve the equation

STEP 2

First, we need to isolate the term with xxx on one side of the equation. We can do this by adding9 to both sides of the equation.−x−9+9=−21+9-x -9 +9 = -21 +9−x−9+9=−21+9

STEP 3

implify the equation.−3x=−21+9-3x = -21 +9−3x=−21+9

STEP 4

Calculate the right side of the equation.−3x=−12-3x = -12−3x=−12So, the first square in the solution should be filled with −12-12−12.

STEP 5

Next, we need to solve for xxx. We can do this by dividing both sides of the equation by −3-3−3.x=−12−3x = \frac{-12}{-3}x=−3−12​

STEP 6

Calculate the value of xxx.x=4x =4x=4So, the second square in the solution should be filled with 444.The solution to the equation −3x−9=−21-3x -9 = -21−3x−9=−21 is x=4x =4x=4.
