What is the value of x in the equation 3x - 9 = 0?

What is the value of x in the equation 3x - 9 = 0?

• A. x = 3
• B. x = 4
• C. x = 9
• D. x = 0

Answer: (A)

To find the value of \( x \) in the equation \( 3x - 9 = 0 \), you can start by isolating the term with \( x \). First, add \( 9 \) to both sides of the equation: \[ 3x - 9 + 9 = 0 + 9 \] This simplifies to: \[ 3x = 9 \] Next, to solve for \( x \), divide both sides by \( 3 \): \[ x = \frac{9}{3} \] This calculation gives you: \[ x = 3 \] Thus, the conclusion that the value of \( x \) is \( 3 \) is verified; this is why the answer is accurate. It demonstrates a clear understanding of the process of solving linear equations, including applying basic algebraic manipulations to isolate the variable.

To find the value of ( x ) in the equation ( 3x - 9 = 0 ), you can start by isolating the term with ( x ). First, add ( 9 ) to both sides of the equation:

[

3x - 9 + 9 = 0 + 9

]

This simplifies to:

[

3x = 9

]

Next, to solve for ( x ), divide both sides by ( 3 ):

[

x = \frac{9}{3}

]

This calculation gives you:

[

x = 3

]

Thus, the conclusion that the value of ( x ) is ( 3 ) is verified; this is why the answer is accurate. It demonstrates a clear understanding of the process of solving linear equations, including applying basic algebraic manipulations to isolate the variable.
