x, student tickets

y, adult tickets

x+y=306

x=2y, 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.

(2y) + y=306

3y=306

y=102 adult tickets sold.
