## Homework Statement

Using matrix algebra calculate the voltage expected across each resister in the circuit diagram.

Only need the simultaneous equations.

## The Attempt at a Solution

-15=6800(I_b-I_a )+2200(I_b-I_c)

15=2200(I_c-I_b )+8200(I_c-I_d)

-25=8200(I_d-I_c )+4700I_d

Thanks for any help.
