Let *[tex \LARGE x] represent the number of true/false questions and *[tex \LARGE y] represent the number of essay questions.


There are 20 questions total, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ =\ 20]


The T/F questions are worth 3 points each so all of the T/F questions are worth *[tex \LARGE 3x] points.  Likewise the essay questions are worth 11 points each, so all of the essay questions are worth *[tex \LARGE 11y] points.  And there are 100 total points.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3x\ +\ 11y\ =\ 100]


Solve the 2X2 system for *[tex \LARGE y]
