All you have to do is get urself back to the original equation, and see what y needs to be in order to get back to that equation. If you dont understand that then do this:

1. Make 0 the subject of the formula
2. Then get it into a form like this :
3. Now, compare it to the original equation,
4. Now determine what y needs to be in order to get that value.
5. Also remember, if , then is also equal to 0.
6. That is often a problem many of my frnds faced.

Hope that helped.
