提出这个问题我猜测你应该在研究生level,因而授之以渔,不提供详细解答过程。
For consumer A: max u1(x,y)=2x1+3lny1, st: p1*x1 + p2*y1 = p1*10 + p2*10
For consumer B: max u2(x,y)=3lnx+5lny, st: p1*x2 + p2*y2 = p1*15
Market clearing condition: x1 + x2 = 10 + 15; Or y1 + y2 = 10 + 0=10 (Based on Warlas Law, you can either one condition to clear the two-goods market.)
Finally, you can get x1, x2, y1, y2 and the relative price P= p1/p2 (note that you cannot get p1 and p2, but only the relative price.)
