Elena and Kiran are playing a board game. After one round, Elena says, 'You earned so many more points than I did. If you earned 5 more points, your score would be twice mine!' Kiran says, 'Oh, I don't think I did that much better. I only scored 9 points higher than you did.' Write a system of equations to represent each student's comment. Be sure to specify what your variables represent. If both students were correct, how many points did each student score? Show your reasoning.
