    The 6 A is 9 A for the problem I'm solving for.

    2. Relevant equations
    Only using KCL

    3. The attempt at a solution

    I tried using KCL @ node a:

    9 = io + i0/4

    I get io = 7.2 A.

    The answer in the book is 6A. What am I doing wrong?

    What about the current through the 8 Ω resistor?

    You should get something like:

    ##6A - i_o - \frac{i_o}{4} - i_x = 0##

    Then using the fact everything is in parallel, you should be able to find what you need.
