Superposition for dependent sources and Pspice

In summary: For number 4, it looks like you're attempting a Δ-Y transformation (or two?). If so, the numbers don't look right to me. Can you describe the steps you're making?in summary, the student is trying to solve a current problem using a dependent current source but is having difficulty understanding the syntax or format. He has uploaded his work for 3 and 4 and notes that at least one of the current values he found doesn't match values he finds when solving the problem using his own method. For #2, he notes that at least one of the current values doesn't agree with values he finds. For #3, he has a different answer this time. Lastly, for #4, he

No, you want to relate Ix to the node voltage. What term wold you include in a node equation for the current in the Ix branch?

Isn't the 8V source removed (suppressed) at this point?

Oh yah good point so could it be v''=-3Ix

Yup, could be!

Heh good because I solved it out and found Ix''=-1.5 and Ix=-.5A
