In the equation 2y - 6 = 0, what is y?

To find the value of ( y ) in the equation ( 2y - 6 = 0 ), you first want to isolate ( y ). Begin by adding 6 to both sides of the equation, giving you ( 2y = 6 ).

Next, to solve for ( y ), divide both sides of the equation by 2. This leads to ( y = \frac{6}{2} ), which simplifies to ( y = 3 ). Therefore, the correct answer is 3.

This process demonstrates the application of basic algebraic techniques used to isolate a variable in an equation, ensuring that the operations performed maintain the equality of the equation.
