    I need to find I3, I2, and I1


    Attempt

    -15= 10i + 20i + 4i ?

    I am not sure how to go about this.

    Am I suppose to use current division rule instead ?

    If someone can kindly explain

    Yeah, I got the answers. Thank you. How come voltage across a circuit is the same?
    Can't it vary?
