When there are variables in the question stem, it’s time to Plug In. For this problem, it’s easier to Plug In if you simplify the equation first. Rearrange the equation to put the variables on opposite sides of the equal sign. 8x = 4y. Then divide both sides by 4 to get that 2x = y. Now, choose some easy numbers such as x = 2 and y = 4. In this case, Quantity B is greater, so eliminate (A) and (C). Next, try something like x = 0 and y = 0. In this case, the two quantities are equal. Eliminate (B), and the correct answer is (D).
