Joseph took a math test with 50 questions. For each correct answer he gets 5 points, and for each question not answered or wrong he loses two points. Joseph scored 124 points on his math test. Which system of equations can be used to determine the number of correct answers x, and the number of questions not answered or wrong, y?

• 5x - 2y = 124

• x + y = 50

• 5x + y = 124

• x + y = 124

• 5x - 2y = 50
