Answer

Bottom of the circuit is considered to be ground.
First we need to find Vx. Vx can be found by voltage division.

    Vx = 24(4 / (6 + 4))
         = 9.6 V

Now, find the voltage at the independent source.

    = .75 * 9.6
    = 7.2

Finally, solve for V1 by using voltage division again.

    V1 = 7.2(3 / (3 + 2))
         = 4.32 V
