The fixed points are determined by solving f(x, y) = x(3 − x − 2y) = 0, g(x, y) = y(2 − x − y) = 0. Evidently, (x, y) = (0, 0) is a fixed point. On the one hand, if only x = 0, then the equation g(x, y) = 0 yields y = 2. On the other hand, if only y = 0, then the equation f(x, y) = 0 yields x = 3. smart financial business accounts
