<p>Back to the strategy of picking numbers! One of the most important things to remember about this strategy is the following:</p>
<p>Most of the time picking numbers only allows you to eliminate answer choices. So don’t just choose the first answer choice that comes out to the correct answer. If multiple answers come out correct you need to pick a new number and start again. But you only have to check the answer choices that haven’t yet been eliminated.</p>
<p>For example, consider the following problem:</p>
<p>Which of the following is equal to (x+66)/22 ?</p>
<p>(A) (x+33)/11<br>
(B) x+3
(C) 3x
(D) x/22+3
(E) (x+3)/11 </p>
<p>Note that if you choose x=0, the answer to the question is 3. Plugging 0 in for x into each answer choice gives the following:</p>
<p>(A) 3
(B) 3
(C) 0
(D) 3
(E) 3/11 </p>
<p>Note that choices (A), (B), and (D) all come out correct. A common mistake would be to choose choice (A) without checking the other choices.</p>
<p>See if you can solve this problem by picking a better number. Then also try to solve it algebraically.</p>
