To find the value of x in the equation −3x+9=−19, you can start by subtracting 9 from both sides of the equation:
−3x+9−9=−19−9
Simplifying, you get:
−3x = −28
Next, divide both sides of the equation by -3 to solve for x:
−3x/−3 = −28/−3
Simplifying further, you get:
x = 28/3 or 9 and 1/3
Therefore, the value of x is 28/3 or 9 and 1/3.
To find the value of x when −3x+9=−19, you can start by isolating the term with x on one side of the equation.
−3x+9=−19
First, you can subtract 9 from both sides of the equation to get rid of the constant term on the left side:
−3x = −19 - 9
−3x = -28
Next, you can divide both sides of the equation by -3 to solve for x:
x = -28 / -3
Simplifying the division:
x = 28 / 3
So, the value of x is 28/3 or 9 and 1/3.
To find the value of x in the equation −3x + 9 = −19, you need to isolate the variable x on one side of the equation. Here's the step-by-step process:
Step 1: Start with the original equation: −3x + 9 = −19.
Step 2: Subtract 9 from both sides of the equation to move the constant term to the other side: −3x = −19 - 9, which simplifies to −3x = −28.
Step 3: Divide both sides of the equation by −3 to solve for x: x = (-28) / (-3), which simplifies to x = 28/3.
The value of x is 28/3 or 9 and 1/3 (as a mixed number). So, the correct answer is 9 and 1/3 or 9.33 (rounded to two decimal places).
