Calculating e3 using Node Equations: Solving for e3 in a Circuit System

[wilsonb]

Homework Statement

I approached this by doing the node equation of e3:

(e3-(-V)-e2)G1 + (e3-e2)G2 + I = 0

Homework Equations

which gives:

e3/3 + 5/3 + e3/5 + 3 = 0

multiply out the fractions

5e3 + 25 + 3e3 + 45 = 0

The Attempt at a Solution

so:

8e3 = -70

giving e3 = -8.75
