Hi,

A test consists of multiple choice questionshighlight%28x%29 worth 3 points and essay questionshighlight%28y%29 worth 5 points.

The test has 17 questions that are worth a total of 65 points.

  3x + 5y = 65       | x+y = 17  0r   y = 17-x

 3x + 5(17-x) = 65

   -2x = -20

     x = 10, number of multiple choice questons,  7 essay questions

and...

 30+%2B+35+=+65
