x=4
To solve the equation −3x−9=−21, we can follow the steps provided:
Step 1: Start with the equation: −3x−9=−21
Step 2: To eliminate the -9 on the left side of the equation, add 9 to both sides: (-3x - 9) + 9 = (-21) + 9
This yields: -3x = -12
Step 3: To solve for x, divide both sides of the equation by -3: -3x / -3 = -12 / -3
This simplifies to: x = 4.
Therefore, the solution to the equation −3x−9=−21 is x = 4.
To complete the solution, let's follow the steps given in the equation −3x−9=−21.
Step 1: Start with the given equation −3x−9=−21.
Step 2: Add 9 to both sides of the equation:
−3x - 9 + 9 = -21 + 9
Simplifying: -3x = -12
Step 3: Divide both sides of the equation by -3:
(-3x) / -3 = -12 / -3
Simplifying: x = 4
Hence, the solution to the equation −3x−9=−21 is x = 4.

Solve 5−6x=−7 .(1 point) x=
To solve the equation 5−6x=−7, we can follow these steps:
Step 1: Start with the equation: 5-6x = -7
Step 2: Subtract 5 from both sides of the equation:
(5 - 6x) - 5 = -7 - 5
Simplifying: -6x = -12
Step 3: Divide both sides of the equation by -6:
(-6x) / -6 = -12 / -6
Simplifying: x = 2
Hence, the solution to the equation 5−6x=−7 is x = 2.
The equation 5/3x+11/3=−4/3 is solved as follows. Fill in the correct numbers to complete the solution.(1 point) 5/3x+11/3=−4/3 5/3x= Subtract 113 from both sides. x= Multiply both sides by 3/5 , the reciprocal of 5/3 .
To solve the equation 5/3x+11/3=−4/3, we can follow these steps:
Step 1: Start with the equation: 5/3x + 11/3 = -4/3
Step 2: Subtract 11/3 from both sides of the equation:
(5/3x + 11/3) - 11/3 = -4/3 - 11/3
Simplifying: 5/3x = -15/3
Step 3: Multiply both sides of the equation by 3/5, the reciprocal of 5/3:
(5/3x)(3/5) = (-15/3)(3/5)
Simplifying: x = -45/15
Step 4: Simplify the fraction:
x = -3
Hence, the solution to the equation 5/3x+11/3=−4/3 is x = -3.
