Let represent the number of true/false questions and represent the number of essay questions.

There are 20 questions total, so:



The T/F questions are worth 3 points each so all of the T/F questions are worth points. Likewise the essay questions are worth 11 points each, so all of the essay questions are worth points. And there are 100 total points.
