Based on the diagram, I am to find three currents: I₁, I₂and I₃ using Kirchoff's Law and then setting up a linear algebra matrix to find the currents.

When I did this, I was not finding the right ones (I got numbers like 3/2 and 0, but the correct answers are I₁ = 1/28, I₂ = 3/7, I₃ = 27/28. I think the set up may be incorrect, so I am looking for guidance in understanding how to find these.

Thank you for any helpful instruction you can provide for better understanding and learning purposes.
