I'll start you off with the transition matrix. The (1,1) entry is the probability an X voter stays X, the (1,2) entry is the probability an X voter changes to Y, the (2,1) entry is the probability a Y voter changes to X, and the (2,2) entry is the probability a Y voter stays Y :

3/4 1/4

well that's the hard part, since now all one has to do is calculate 0 = det(xI - A) =

(x - 3/4)(x - 2/3) - (1/12), and solve for x.
