Intensity through each power source

  1. Feb 18, 2013 #1
    1. The problem statement, all variables and given/known data


    Please help me to solve this type of circuits...
    I want to find the intensity through each power source and what voltage does the voltmeter indicates.

    2. Relevant equations

    I=I1+I2

    3. The attempt at a solution
    don't know

    Re: circuit

    To work out the current flowing around the black loop you could start by simplifying the circuit. How do you simplify two resistors in series? Two voltage sources in series?

    36v-i(9)-12v=0
    i=2.66A
