First Loop

I may be forgetting my circuit diagrams, but isn't the voltage drop across the opposite sign of the drop across in the first loop? In which case the first equation would be . If so, this means the rest of the questions for 3 must be redone.

Hi Alistair,

You're right about the first equation, but there is no need to redo the problem- I just made a typo in that equation. You can see that the matrix equation described below is correct.

Also, I'm pretty sure the answers to parts (b) and (c) are correct because I checked them with an online tool.
