## Homework Statement

Hello. This is my first post, hoping its in the right section. Now when it comes to physics I dont really have a clue, biology is my strong point. But still need to know this. When making X the subject what do I need to learn? I know the basics such as y = X - 3 is X = y + 3 ect. But need to know when to divide both sides of the equation by another thing in in the equation. Or what do I do when there is a squared or brackets involved. Sorry for my stupidity. Im trying. Any help appreciated. Thanks for reading
