Solve for y: 5y - 10 = 0.

To solve the equation ( 5y - 10 = 0 ), the first step is to isolate the term containing ( y ). To do this, you can add 10 to both sides of the equation. This simplifies the equation to:

[ 5y = 10 ]

Next, to solve for ( y ), divide both sides by 5:

[ y = \frac{10}{5} ]

Calculating this gives:

[ y = 2 ]

This means that the correct solution to the equation ( 5y - 10 = 0 ) is indeed 2, which aligns with the given answer. Finding the value of ( y ) in this way ensures that the equation balances, confirming that 2 is the correct solution.
