WILL REWARD!!! HELP

One month Ivanna rented 8movies and 3 video games for a total of $51
. The next month she rented 2 movies and 5 video games for a total of $34
. Find the rental cost for each movie and each video game.

Answer 1

8m+3v=51

2m+5v =34

multiply the 2nd equation by -4

-8m -20v = -136

add 1 and the modified 2nd equation together

8m+3v=51

-8m -20v = -136

------------------------

-17v = -85

divide by -17

v=5

substitute into 1st equation

8m+3v=51

8m +3(5) = 51

8m +15 = 51

subtract 15 from each side

8m =36

m =4.5

Answer: videos are $5.00

movies $4.50
