The selling price of the Horizon is given by the equation D(S) = 222 - 0.60P(S) + 0.35P(H), where D(S) represents the demand for the Horizon, P(S) represents the price of the Horizon, and P(H) represents the price of a related product. The demand for the related product is given by the equation D(H) = 270 + 0.10P(S) - 0.64P(H). Solve the system of equations to find the equiLiBrium prices of the Horizon and the related product.
