Your nodal equations are correct.

To check your work you should use some kind of math software. I use an old version of Derive. Nice thing about old versions of software is that they actually included a user manual you could read offline. Now everyhone seems to refuse to provide hardcopy user manuals (which is why I did not get a newer version of Derive myself).

Thanks dude.

I think I'll check out Derive, but probably for the pset after this one. I'd rather work on this pset now rather than learn how to use Derive.

If you do get Derive, if you let me know I can show you in a minute how to solve simultaneous equations like the ones you have here. Especially if it's the old DOS version. Get that one if you can, it should come with a hardcopy user manual.
Send me a note if you want.
