Hi,

I was trying to run the following command:

DSolve[{Derivative[1][x][t] == x[t] (2 - 2 x[t] - y[t]),
Derivative[1][y][t] == (3 - x[t] - 3 y[t]) y[t]}, {x, y}, t]

but it take a while to run and only returns DSolve[{Derivative[1][x][t] == x[t] (2 - 2 x[t] - y[t]),
Derivative[1][y][t] == (3 - x[t] - 3 y[t]) y[t]}, {x[t], y[t]}, t].

what am I doing wrong? when I simplify one of the two expressions, either x' or y' it works perfect... but not this one...

HELP!
