x, student tickets
y, adult tickets

system%28x%2By=306%2Cx=2y%29, exact translation of the description into a system of equations. Solve for the value of y.

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.

%282y%29%2By=306
3y=306
y=102----------adult tickets sold.
