Question 558421
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of questions she got right and *[tex \Large y] represent the number of questions she got wrong.


The total number of questions is 50 so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ =\ 50]


The value of right answers is 2, the value of wrong answers is 1, and the total value of the sum of the right answers and the wrong answers is 67, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ +\ y\ =\ 67]


Solve the 2X2 system for *[tex \Large (x, y)]
