Find the equation of the contract curve and also the competitive equilibrium

Styles There are two consumers A and B , and two commodities x and y. UA = xay(1-a): Utility function of consumer A. WA : consumer A's endowment of good x wx : consumer A's endowment of good y UB = 2XB + VB: Utility function of consumer B. WB: consumer B's endowment of good x WB : consumer B's endowment of good y H Px: price of good x Py: price of good y. p = Px/p. : relative price of good x a. Find the equation of the contract curve. b. Find the competitive equilibrium (p*, XA , YA, XB, VB). Your answer should be in terms of the parameters only
