ANSWER: D. x=2, x=3
You are used to solving for these type of problems by either the bracket methods or, if not possible, via the quadratic formula. However, in a timed multiple choice test, such as the OAT, where time is of the essence in the QR section, the best hint I can give for these type of problems is to work backwards and plug in the answers and see if it makes sense with the equation. With the use of the in-screen calculator, it is faster to do this approach than waste time working it out on the whiteboard.
