Question
100%

I am looking for some help with a Linear Algebra matrix problem involving circuit analysis for Loops A and B as shown in the figure (ignoring the outer loop).

Eventually I am to use an augmented matrix when when reduced yields the three currents, but I applied Kirchoff's Law and my work as attached seems to be incorrect and I'm not sure why.

If I get could get help in understanding how to clearly approach this problem that would be great.  Thank you.
