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

This is out of a book on Excel, where we are solving simultaneous equations. ** However, how do we find the equations for this network in the first place? (image at bottom) **

**2. Relevant equations**

∑ I= 0

∑ V =0

**3. The attempt at a solution**

i1 + i2 + i3 = 2

i6 + i7 +i10 = 3
