The process can be, solve for x in terms of y, already seen as THE second equation of the system; substitute into the other equation, and solve the result for y, and compute.

(2y)+y=306
3y=306
y=102----------adult tickets sold.

x=adult tickets
2x=student tickets
x+2x=306
3x=306
x=102 adult tickets
2x=2*102=204 student tickets
