                An Algebra I test contains 30 questions. Some of the questions are worth 4 points each, and some are worth 2 points each. The total test is worth 100 points. Let f represent the number of questions worth 4 points and t, the number of questions worth 2 points. 
Solve the system by elimination to find how many two-point questions the test contains

    f + t = 30
4f + 2t = 100
4f + 4t = 120
4f + 2t = 100
2t = 20
t = 10
So, f = 20
    
4f + 2t = 100
4f + 4t = 120
4f + 2t = 100
2t = 20
t = 10
So, f = 20
