The point at which a​ company's costs equal its revenues is the ​ break-even point. C represents the​ cost, in​ dollars, of x units of a product and R represents the​ revenue, in​ dollars, from the sale of x units. Find the number of units that must be produced and sold in order to break even. That​ is, find the value of x for which C = R. C = 14x + 36,000 and R = 16x.
