(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

This is the circuit I'm working on:

2. Relevant equations

My equations are:

4.64v=-200I1-800I3

4.64v=750I3+800I2

4.64v=-200I1-750I3

3. The attempt at a solution

I should have a third unknown in each equation. I not seeing where I'm going wrong. I'm supposed to put this in a 3X3 matrix and have Excel solve for the simultaneous equations. Any help?
