There are 2 main things to know
1) You have to get all by itself on one side of the equation
2) Anything you do to one side, you MUST do to the other side
So, first
Subtract from both sides
This is the same thing as adding these 2 equations together

Notice that the and the on the right side cancel
So, now you have

Now divide both sides by

On the right side, the in the denominator cancels the
in the numerator
Now you have

Now just rewrite the equation in the opposite direction

And that's the answer
