Helppp, is for my final exam The final exam for Miguel's math class is worth 120 points and will be comprised of an assortment of 50 multiple choice and free-response questions. Each multiple choice question is worth 2 points and each free-response question is worth 3 points. Which system of linear equations can be used to find x , the number of multiple choice questions on the final, and y , the number of free-response questions?
{ x + y = 120 3 x + 2 y = 50

{ x + y = 120 2 x + 3 y = 50

{ x + y = 50 2 x + 3 y = 120

{ x + y = 50 3 x + 2 y = 120
