Solve for 

Possible Answers:

Correct answer:

Explanation:

In order to solve for , we need to move the rest of the variables to the other side so that  is by itself.

Currently there are two other variables near  and . In order to solve the equation, we will need to move them to the other side with .

Let's start by subtracting  from both sides.

Now let's add  to both sides.

Because there are no numbers and that all of our variables are different we cannot do anything else to this equation. 

Our answer is
