    One month Boris rented 

    5 movies and 6 video games for a total of $37.

    The next month he rented 

    3 movies and 2 video games for a total of $19. 

    5m + 6v = 37

    3m + 2v = 19

    m = 5.00, v = 2.00

    The rental cost for each movie was $5.00 

    and each video game was $2.00

    Seriously? Who rents movies anymore? Is this problem in a textbook written in the 90s?

    OK- this is why you need algebra. You let a letter stand for movies and one for video games. The standard is to use x and y, but you can use m and v- it really doesn't make any difference. You know two things:

    5m+6v equals 47

    3m + 2v=19.

    Solve one equation for m

    5m=47 - 6v

    m=47-6v

    Now substitute that in the 2nd equation so you only have one variable, and solve for it.

    Elementary eighth grade/high school algebra:

    5m + 6g = $47

    3m + 2g = $19

    I'll let you do the rest.

    PS:  This should be in the Education/Homework section.
