A soccer player gets 2 points for a goal and 1 point for an assist. If the combined number of goals and assists that a player has is 24, and the total number of points that the player has is 42, which system of equations can be used to determine the number of goals and assists the player has? Assume g represents the number of goals and a represents the number of assists. g + a = 24. g + 2 a = 42. g + a = 24. 2 g + a = 42. g + a = 42. g + 2 a = 24. g + a = 42. 2 g + a = 24.
