8th Grade Algebra

posted by .

1) An exam will have 20 questions worth a total of 100 points. There will be True-False questions worth 3 points each and short essay questions worth 11 points each. Several students ask how many essay questions there will be, but the teacher won't tell. How many essay questions will there be.

    let x = number of true-false questions
    let y = number of essay questions

    x + y = 20
    3x + 11 y = 100

    Solve those two equations. I assume you know how. Substitution is one way.
