Calculate the current i3 in the following configuration:

http://capa-new.colorado.edu/msuphysicslib/Graphics/Gtype57/prob06_kirch.gif

EMF_1 = 6 V

EMF_2 = 3 V

R_1 = 70 Ohm

R_3 = 20 Ohm

2. Relevant equations

I know that V=IR so I=V/R

but because there are 2 batteries i am just having a little bit of a problem.

3. The attempt at a solution

tried adding up the batteries but it does not seem to be working
