## Homework Statement

Find IA, IB, IC, I1, I2, V

_{0}, VA

## Homework Equations

## The Attempt at a Solution

(V

_{0}/10) = IA-IB

For IA: 10v + 10(IA+IC) + (IA-IB)=0

11(IA) - (IB) + 10(IC) = -10v

For IB: -(IB-IA) - 20(IB+IC) - 10(IB) = 0

IA - 31(IB) - 20(IC) = 0

For IC: 10(IA+IC) - 20(IC+IB) - 10(IC) = 0

10(IA) - 20(IB) - 20(IC) = 0

I then put these equations into a matrix (Sorry I don't know how to put them into a matrix on here) and used an online matrix calculator to get the currents:

IA= -0.4A

IB=(18/55)A

IC=(-29/55)A

So then I plugged these values into this formula:

(V

_{0}/10) = IA-IB

And got V

_{0}= -7.3V

But when I used v=iR to see if I would get the same thing I got

v=(-29/55)(10)= -5.27v

What am I doing wrong?
