Consider these three changes in the possible distributions of six gaseous particles within three interconnected boxes. Which change has a positive ÎS?

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

answer: y=0 if that is what u r looking for
