operational amplifier - analyzing op amp circuit


I was wondering what would be the voltage of the node which is connected to 1K and 4K resistors? sometimes I think I need to add up the two voltage sources( 13-2=11V) but I wonder maybe it is just 13V . can you give me some insights please? I am really carious to know when can we add up and when we cannot? what if the polarity of 2V source was the other way around? ( I think then that would 13+2=15V).


The main goal is to find V0 here is what I have tried so far. I would appreciate your comments on that.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
