    px - qy = 1
    py + qx = 0

    Express p in terms of x and y. Then do the same for q.

    Could anyone show me how this is done? I know the answer but I can't work out how they have done it. It is really annoying me! lol

    Thanks

    Thanks dude. It's multiply top equation by x and then bottom by y. That way I get an equation which has only p in it. And then substitute it back in to the other.
