A test has twenty questions worth 100 points. The test consists of True/False questions worth 3 points each and multiple choice questions worth 11 points each. This system of equations can be used to find how much of each question type he has. x + y = 20
3x + 11y = 100

"X" represents the number of true/false question and "y" represents the multiple choice questions.
The solution to the system is (15, 5). What is the correct interpretation of this solution.
