## The Attempt at a Solution

I am a little lost on this one. It should be straightforward, but I don't know what the approach is. Any thoughts on what technique I use to start this? I know that some of the current from the ideal source flows through the resistor and some through the voltage source (or sink?), but I am not sure how to determine how much?

Is it true to say that since the voltage sink (I am pretty sure it is a sink due to polarities of resistor and voltage element) that they must share voltage? I think that is the hint my professor gave, but I thought that voltage divides across

*resistors*in parallel and not necessarily a resistor and generic sink in parallel.

Thanks.
