Can someone please explain the solution to a nodal analysis problem to me?

AI Thread Summary
The discussion focuses on a nodal analysis problem where the user seeks clarification on transitioning from nodal equations to a specific solution step. The key equations involved are V=IR and the nodal equations for two nodes, V1 and V2. A suggestion is made to express the current Ix in terms of V1 and its corresponding resistance, and then substitute this into the second equation. The user is encouraged to solve the first and second equations simultaneously to find V2. The conversation emphasizes the mechanics of solving these equations effectively.

Homework Equations



V=IR, Nodal Analysis

The Attempt at a Solution



1 and 2 in the diagram are the nodal equations. Considering that the left node is V1 and that the right node is V2. I don't know how to get from the nodal equations to step 3. I know that you go from step 3 to step 4 using V=IR.

I tried solving the nodal equations to get to step 3...

Can someone please work it out for me? Thank you

You write Ix in terms of V1 and the resistance that Ix flows through, and substitute that into the 2nd equation. Then just solve the 1st and 2nd equations simultaneously for V2.

Does that help? Or are you having trouble with the mechanics of solving equations 1 & 2 simultaneously?
