    Let i_1 be the current from E1 towards R1

    and i_2 be the current from E2 towards R2

    -----
    Use Kirchhoff's loop law

    We get

    For the loop of potential E1

    6 = 3i_1 + 4(i_1 + i_2)

    For loop of E2

    12 = 12i_2 + 4(i_1 + i_2)

    --------
    two equations and two unknowns....

    i_3 = i_1 + i_2
    --------


    I hope this one is clear than the one I told you there... :-)
