![]() But remember, you are solving for 3 x + 1, not just x. The most common mistake is to solve for x, which is 3, and mistakenly choose A as your answer. Solving for x leaves x = 3, then substituting into 3 x + 1 gives 3(3) + 1, or 10. You should first circle or underline 3 x + 1 because this is what you are solving for.

Participants had to first give their System 1 answer, or their initial hunch, and then were allowed to give a System 2 answer, which was supposed to be more thought-through.
