given the following:

http://lh6.ggpht.com/_H4Iz7SmBrbk/Sg04JIIg9vI/AAAAAAAAA-o/xDycbG90Gmc/s720/C.jpg

and given that

ε1=3V

ε2=2V

R1=1Ω

R2=2Ω

R3=3Ω

i am asked to find the current flowing throiught R1,R2, R3

what i did was

I

I

but i am short of one equation to solve this, what i would like to do is somehow find R

had ε1 noot been there i would have said R

how can i solve this?

i am asked to find the current flowing throiught R1,R2, R3

what i did was

I

_{3}=I_{2}+I_{1}I

_{1}R_{1}-I_{2}R_{2}=ε_{1}but i am short of one equation to solve this, what i would like to do is somehow find R

_{12}, as an the sum of R1 and R2, but my problem is that i have ε1 between them and i have no idea how to tackle this,had ε1 noot been there i would have said R

_{12}=(1/R_{1}+1/R_{2)-1}and then i could make a third equation using this.how can i solve this?
