This is a class about linear equations not about electrical engineering:
Well I know that the sum of all the voltage drops around a closed loop is equal to the total voltage in the loop so.I'm guessing here:I1+I2+I3= 0
I2-2I3= 3
I1+ I2 = 4
Homework Statement
"Determine the currents in the various branches"
Homework Equations
The one I am stuck on is 6.
The Attempt at a Solution
I know there is 3 equations, I believe one of them is I1 + I2= 3 and a second is 4= 2I3+I2 ??
but I am not sure if that is correct...
