General Equilibrium , please help

General equilibrium - There are two goods (1 and 2) and two agents (A and B). Preferences are described by whirls-\"'31) : 9:119:31, \"8(171815'323) : 111-111{:17IB,21'ZB}, Where 93114 is the quantity of good 1 consumed by A, 33% is the quantity of good 2 consumed by A, 3:13 is the quantity of good 1 consumed by B, and 3:23 is the quantity of good 2 consumed by B. The initial allocations are 8A 2 (3,0), 83 = (1,4). (a) Sketch the Edgeworth box with 1) several indifference curves for both agents} 2) the initial allocation, and 3) the contract curves (b) Find the competitive equilibrium {XA, X3, E} where X4 2 (5321,5331) and XS 2 (5:55:23)
