What is the value of x when −3x+9=−19? (1 point)
9
-9
3 2/3
-3 2/3
To solve the equation, we can first subtract 9 from both sides:
-3x + 9 - 9 = -19 - 9
This simplifies to:
-3x = -28
Next, we can divide both sides by -3 to solve for x:
x = -28 / -3
Therefore, x = 9 1/3 or -3 2/3.
The correct answer is -3 2/3.
To find the value of x in the equation -3x + 9 = -19, follow these steps:
Step 1: Begin by isolating the term with x by subtracting 9 from both sides of the equation.
-3x + 9 - 9 = -19 - 9
This simplifies to:
-3x = -28
Step 2: Divide both sides of the equation by -3 to solve for x.
-3x / -3 = -28 / -3
This becomes:
x = 28 / 3
Step 3: Simplify the fraction.
The fraction 28 / 3 can be expressed as a mixed number by dividing 28 by 3. The quotient is 9 with a remainder of 1.
Therefore, the final answer is:
x = 9 1/3
To find the value of x when -3x + 9 = -19, we need to isolate x on one side of the equation.
First, let's simplify the equation by subtracting 9 from both sides:
-3x + 9 - 9 = -19 - 9
This simplifies to:
-3x = -28
Next, divide both sides of the equation by -3 to solve for x:
(-3x) / -3 = (-28) / -3
This simplifies to:
x = 28/3
Therefore, the value of x is 28/3, which is equivalent to 9 1/3 or 3 2/3.
