Solve for y: 3y – 9 = 0.

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (C)

To solve for \( y \) in the equation \( 3y - 9 = 0 \), you first want to isolate \( y \). Begin by adding \( 9 \) to both sides of the equation, which helps to eliminate the constant term on the left side: \[ 3y - 9 + 9 = 0 + 9 \] \[ 3y = 9 \] Next, to find \( y \), divide both sides by \( 3 \): \[ \frac{3y}{3} = \frac{9}{3} \] \[ y = 3 \] This tells us that the value of \( y \) that satisfies the equation \( 3y - 9 = 0 \) is \( 3 \). Thus, the correct answer reflects that when \( y \) is \( 3 \), the original equation becomes \( 3(3) - 9 = 0 \), confirming that the equation holds true. Understanding the process of isolating \( y \) is crucial here, as it illustrates the steps needed to solve for a variable in a linear equation. This method can be applied to other similar equations, enhancing overall problem-solving

To solve for ( y ) in the equation ( 3y - 9 = 0 ), you first want to isolate ( y ). Begin by adding ( 9 ) to both sides of the equation, which helps to eliminate the constant term on the left side:

[ 3y - 9 + 9 = 0 + 9 ]

[ 3y = 9 ]

Next, to find ( y ), divide both sides by ( 3 ):

[ \frac{3y}{3} = \frac{9}{3} ]

[ y = 3 ]

This tells us that the value of ( y ) that satisfies the equation ( 3y - 9 = 0 ) is ( 3 ).

Thus, the correct answer reflects that when ( y ) is ( 3 ), the original equation becomes ( 3(3) - 9 = 0 ), confirming that the equation holds true.
