I am just not sure how they applied nodal analysis here to find that ##I_s = \frac{12}{12} + \frac{12}{6} + \frac{128}{4}##. If I'm not mistaken, they are just finding V/R, correct? But isn't the voltage in ALL the resistors dependent in some way on both the 12 V source attached and also the dependent voltage source? Why does it seem like they only included the dependent voltage only on the 4ohm resistor? Is their solution correct?
