Please find producer & consumer surplus as well. Thank you!

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. 4 1 D(X) = - 15 x + 21, S(x) = -x+3 (a) Find the equilibrium point. (Type an ordered pair, using integers or decimals.)
