How do you solve this ???
galina1969 [7]
First you have to figure out how much a video game costs and how much a used one costs
Then you plug in the costs of the video games into Janets equation 120=3x+y
(x= video games and y=used video games)
Then you subtract the cost of video games  from 120 and then divide that answer by the cost of used video games and that should give you how many used video games she can get
