How to solve current source prb W/O using Nodal Analysis?
Yes there is an alternative to this problem.  First, note that you have three resistors in parallel with each other.  Put 4k in parallel with 10k which gives you 2.857kOhms.  Then, take 2.857kOhms in parallel with 3kOhms and that will give you 1.463kOhms.  Finally, you can multiply 1.463kOhms to 10mA and you will get a voltage of 14.6V.  The current is in the opposite direction as conventional current flow so the voltage potential will be -14.6V across 10kOhms resistor.  The potential voltage will be the same at all nodes.
