    Kirchoff's Law

    I have 3 equations.

    -I1+I2-I3 =0

    I1R1+I2R2 = E1

    -I2R2-I3R3 = -E2

    And the values I have are:

    R1=98.2
    R2=985
    R3=324.4

    E1 = 1.567
    E3 = 1.532

    Find the I's

    Tried putting all the equations together, but its not going well.

    Have you tried substituting I1 in the second equation by I2 - I3?

    Then, you use simultaneous equations with the equation you get and the last equation.
