Example Question #231 : Algebra 1

Solve for :

.

Possible Answers:

Correct answer:

Explanation:

In order to solve for in the above equation, we must isolate it on one side of the equation. We can do this by applying an operation to that is the inverse (opposite) of what's currently being applied to .

Given , we see that is being multiplied by , so we need to divide both sides of the equation by  (or, equivalently, multiply by ) to isolate :
