Hi! I'm working on a program to extract guitar tracks from an mp3 file..

ive come up with the psuedocode, but , im not that good at the math needed to actually solve the algorithm. if someone can help me. i'd really appreciate it.

this is what ive got so far

a = guitar
b = vocals
c = drums
d = bass

a+b+c+d=song

how can i solve for a?
