The equation given is 5y - 0. First, we can simplify this to 5y = 0 because subtracting 0 from anything does not change its value.
Next, to solve for y, we should isolate y on one side of the equation. We achieve this by dividing the entire equation by 5, as it is the coefficient of y.
Doing so, we get:
5y ÷ 5 = 0 ÷ 5.
Simplifying this equation, we find y = 0 ÷ 5.
And as we know, any number divided by itself is 1, and any number times 0 is 0. Therefore, 0 ÷ 5 = 0.
So, the solution to the equation 5y = 0 is y = 0.
