    You have your terms reversed on the right side of your current equation:
    (9 cos (5t) - 6) / 3 = (6 - Vout) / 4

    Legend! Thanks very much for pointing out that blunder. Wow but the way i did that is so much simpler than the way that the teacher did it. I was worried that there was something conceptually wrong with the way i was doing it.

    Cheers
