    Unfortunately your analysis is wrong. As an example, I take Kirchoff's Law for R3, R4 and R5. It should be that I_{R3}=I_{R4}+I_{R5}, but 0.36 isn't equal to 0.008+0.055.

    Start over. You have calculated correctly the equivalent resistances and the current that the source provides. This current flows through R1 and splits between R2 and R3. Kirchoff's Current Law commands that I_{R1}=I_{R2}+I_{R3}. Use current division formula to find the current that flows through RS1 and R2.

    Is that clear?

    Once you calculated the I total and R total, you can apply KVL and KCL to fill in some areas and use Ohms Law to compute the rest.

    Georacer is correct. Apply Kirchoff's laws and you'll work through this in no time.
