    how many gates are created for Q+ using all original and inverted variables?
    dont want the answer, but a way of solving it? i know it has 3 flipflops and 8states.

    You would probably use a Karnaugh map to minimize the combinatorial logic. Can you use gates with more than 2 inputs? Have you drawn the State Diagrams associated with this problem?

    Is u an output and not counted in the Q+ logic gate total? And if both x and x' are given, isn't 10 the obvious answer if the equations are implemented exactly as written?
