Circuits Assignment

Pay attention to the polarity of the voltage and current sources...be aware of the direction of current and the polarity of the voltage drops.  Some current may add, some may subtract...

Redraw the circuits as needed.  Sometimes redrawing it in a form you recognize makes the problem easier.

Make sure you have correct units and powers of 10.  Don't say the answer is 10....it must have units  (10mA, 10V, etc...)  If the answer is mA, do not say uA...

I think two days should be enough time to get it done but email me if you need more time.

On problem 1, I want the voltage across R2  (I know it says VR1 next to it but I want the voltage across R2).    You need to get the resultant current in that branch, just like we did before and when you get that final resultant current, you should be able to get the resultant voltage across R2.
