I have solved step a, can you help solve steps b and c

D(x) is the price, in dollars per unit, that consumers are willing to pay for x units of an item, and S(x) is the price, in dollars per unit, that producers are willing to accept for x units. Find (a) the equilibrium point, (b) the consumer surplus at the equilibrium point, and (c) the producer surplus at the equilibrium point. 7 1 D(x)= -x+20, S(x)= x+2 (3) Find the equilibrium point. (20,6) (Type an ordered pair, using integers or decimals.) (b) Find the consumer surplus at the equilibrium point. $|:| (Type an integer or a decimal.)
