If I were to just consider those 4 connections, wouldn't that mean the current would just be the minus of what I obtained in my solution? or should the values be the one posted using the MNA method?

I would use MNA but a 5x5 matrice is not very attractive...

yeah...ok you lost me there :S. I can't figure out which is the four connections?

So for Node 4 I am just essentially showing that the currents through the resistors entering the node is equal to the current found at the current source. As for node 2, I am showing that the current at the battery leg connected to node 2 is equal to the currents through the resistors...

Thank you very much for your time and help! Unfortunately I still have another question "Using the voltages at each node calculate the current for nodes 2 & 4 and show Kirchhoff’s Current Law (KCL) holds for each of these nodes." I think I am mostly having trouble interpreting this question...

I was using cramers rule. I did spot another error that I made. I forgot to multiply the 2 by 4 when trying to eliminate the denominators to form the matrice. So anyways here are my new set of solutions which I believe look much better V1= 7.14 or 50/7 V2= -4.857 or -34/7 V3= 4.734 or...

I am completely unsure on how I can find the current at node 2 and 4 and show KCL holds for each though... Do I just find the nodal equation for node 2 and node 4 and find the current using the voltages that I have already derived earlier to find the total current in each node?

I realized I made a mistake at node 3, It should be -V1/10. Anyways here are the new voltages I came up withV1 = 8.214 V2 =-3.7857 V3 = 6.57 V4 = 4.4

So I take the super node and consider it as a combined node consisting of node 1 and node 2? Here is my new system of equations and the voltages I got from each node I am unsure if it correct or not as the values I calculated for V3 do not seem to be very attractive.

Homework Statement I have a circuit and I need to find the Nodal Equations that would mathematically describe the circuit, then proceed to finding the voltages at each node using Cramers rule and the currents at nodes 2 and 4. I don't think I would have much of a problem utilising Cramers...
