1. The problem statement, all variables and given/known data
I approached this by doing the node equation of e3:

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




2. Relevant equations
which gives:

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

multiply out the fractions

5e3 + 25 + 3e3 + 45 = 0



3. The attempt at a solution

so:

8e3 = -70

giving e3 = -8.75

Approached what? There's no problem statement.
