(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Finding potential at certain points in circuit

1. The problem statement, all variables and given/known data

Calculate the potential of [tex]V_1[/tex] and [tex]V_2[/tex]

See attached circuit configuration (circuit2.gif)

2. Relevant equations

Ohms law: U = RI

Kirchhoff's laws

3. The attempt at a solution

I tried to solve it with superposition but my teacher says I've got the wrong sign for [tex]V_2[/tex].

No matter how I try, I get a positive potential for [tex]V_2[/tex].

I've attached my solution (solution.jpg)

Any suggestions?
