x and y;
7%2B30%2F60=x%2By
really only need one variable;
x%2Bx%2B12%2F60=7%2B30%2F60------------x time in minutes for shorter song. Solve.

2x%2B12%2F60=7%2B30%2F60
120x%2B12=420%2B30
120x=420%2B30-12
120x=438
x=438%2F120
x=3.65


Short Song is 3 minutes 39 seconds.
Longer Song is 3 minutes 51 seconds.
