Ok " game stop sells both songs and pictures. For every picture it's 650 kilobytes and for every song it's 2200 kilobytes. On Thursday there was a total of 18,150 kilobytes, and 16 files where downloaded. Determine how many pictures and songs were sold IN TWO EQUATIONS. X for the number of pictures and y for the songs. I need two equations.

you can proceed like this,

650 kb for a pic
and 2200kb for song ( 650 + 1550)

total= 18150 kb and 16 files

so, 650 kb each in both pic and song = 16 * 650= 10400

remaining = 18150-10400 = 7750 , which is contributed by additional 1550 of songs that is
7750/1550 = 5

so, a total of 5 songs and 11 pictures were sold..

hope it helped
