Backsolving works like this:
The answer choices to problems in the math section are usually ordered in the form of smallest to greatest or vice versa. Plug answer C into the problem. If it turns out to be correct, awesome, luck was on your side. If not, look at what you get. If C was too small of an answer, then not only can you rule out answer C, but also the two other responses smaller than it, leaving you with only one more answer to plug in. Out of the two remaining answer choices, if you plug one of them in and it is incorrect, simply by process of elimination, the remaining response is your answer. This is very good for problems that seem too complex to quickly work out, and can save you several minutes of time, allowing you to use that time for other problems.
