Solving a word problem using a system of linear equations of the form Ax + By = C

Question

One month Karen rented 5 movies and 3 video games for a total of $37. The next month she rented 2 movies and 6 video games for a total of $40. Find the rental cost for each movie and each video game.

Answer 1

5m + 3v = 37

2m + 6v = 40

5m + 3v = 37

m + 3v = 20

4m = 17

m = 17/4 = 4.25

then v = 5.25
