Kirchoff's Laws Current [2]

1. The problem statement, all variables and given/known data
Determine the magnitudes and directions of the currents through each resistor shown in Fig. 19-38. The batteries have emfs of [PLAIN]http://www.webassign.net/images/scriptE.gif1 [Broken] = 9.0 V and [PLAIN]http://www.webassign.net/images/scriptE.gif2 [Broken] = 17.0 V and the resistors have values of R1 = 15 [PLAIN]http://www.webassign.net/images/omegacap.gif, [Broken] R2 = 20 [PLAIN]http://www.webassign.net/images/omegacap.gif, [Broken] andR3 = 34[PLAIN]http://www.webassign.net/images/omegacap.gif. [Broken]

2. Relevant equations
Kirchoff's Loop Rule: I1+I2+I3=0
Kirchoff's Series Law?: V1+V2+V3=0

3. The attempt at a solution
I've actually gotten the direction for all three, I just need some serious help calculating the magnitudes.
