Kendra was given three gift certificates for her birthday, each worth 333 points, for a music service. in the past kendra has downloaded five songs and seven videos for a total of 295 points. another time she downloaded ten songs and three videos for a total of 150. what is the most songs that kendra can get with her certificates if she doesn’t buy any videos?

Let x be the number of song points.
Let y be the number of videos points.

We have the first expression:
5x + 7y = 295

We have the second expression:
10x + 3y=150

Solve for y and x:
x = (295 -7y)/5
10 ((295-7y)/5) + 3y  = 150
590 - 14y + 3y =150
590 - 150 = 14y -3y
y=40 points

solving for x:
x = (295-7*40)/5
x=3 points/song

If she buy, all songs for 333 points
number of songs = 333 / 3
number of songs = 111

The answer is 111.
