How do you calculate equillibrium price and quantity given demand and supply functions?

How do you calculate equillibrium price and quantity given demand and supply functions?
At the equilibrium point demand equals supply. Given the demand and supply functions say D and S, first of all equate D=S.
Here both D and S are functions of quantity. i.e., D = f(Q) and S = f (Q).
After equating D = S solve the equation for P and Q.
