## Homework Statement

## Homework Equations

Node Voltage Method

V=IR

## The Attempt at a Solution

So I am very confused about the node voltage method. For this example, the first equation makes sense to me.

**Current in equals current out.**6A in and then the rest makes sense. Is this how you do node voltage method? Just look at the currents going in and out? And then forming equations? If so the second equation doesn't make sense to me. I was told by another student who took circuit analysis that the second equation I wrote in the picture below is correct. I don't understand why. It doesn't follow the current in = current out logic. I was also told that current leaving the node is positive and entering is negative, but that logic doesn't seem to agree with the "correct" equation. With that logic I would get:

(

**V2-0)/2 + 2A - (V2-V1)/3 = 0**

Why is that wrong?

Solution:

**EDIT* Using the equations in the picture, I get values of V1=16V and V2=4V. So I get nice values, but I am still not sure why this works if this is the correct method. Sorry for the multiple edits. I kept messing up my matrix**
