I'm having real difficulty picturing how the current is flowing in this circuit with the given solution.

From the 5v source into node [tex] v_2[/tex] is the current flowing from left to

right into this node?

These are the nodal equations that I would use to solve this problem, however they are wrong. Why?

At node two I would have the current flowing from left to right from the source into this node. I would have the 6mA flowing into this node. Finally I would have a current flowing out of this node from left to right. So I have 2 currents entering this node and one leaving

[tex] \frac{V_2-5}{200} + 6mA = \frac{V_0-V_2}{6000}[/tex]

at node two

[tex]\frac{V_0-V_2}{6000} = \frac{V_0-(-6)}{3000}[/tex]
