Dependent Voltage Source KCL question

  1. Apr 22, 2010 #1
    I'm having trouble figuring out the KCL portion of this problem.

    I have no idea how in the world the solution does from;

    (2-v)/20 = (Vx-2Vx)/8 - (Vx-8)/4

    to;

    17V - 18Vx = 84

    it doesn't seem to make sense; but neither does my solution. i think i'm missing some concept here but cannot put my figure on it.

    Thanks.

    By eyeballing it, I'd say the solutions manual probably multiplied the entire equation by some constant to make all the fractions go away.
