Default Please help solve this 12V electrical circuit puzzle

I'm working on a puzzle (game) that I can't seem to figure out.

Both puzzles are on 12 volt electrical circuits with
incandescent lights on the top puzzle and LED lights on the bottom puzzle.

The answer for the top puzzle should be something in the neighborhood of
33 and the answer to the bottom puzzle should be in the neighborhood of
-112.

I have no information about what the numbers given represent. I've
tried a few calculations solving for watts, amps and ohms and I can't
seem to come anywhere near the expected results.

I'm thinking there is something in the way they are configured that
makes this more of a simple add-em-up type of solution.

Any help or hints would be greatly appreciated!

Hmmm,
Little more than a basic Ohm's law. Apply Thevenin Norton's and/or
Kirchoff's law.
