can you please explain what a supernode is, how do I apply it in this question.
To find the value of V1 and V2 by super-node concept in the given circuit:
Super-node: This concept is used in nodal analysis method. When an independent voltage source is connected between two non-reference nodes then the analysis is done by considering both nodes as one node and that equivalent node is called super-node.
Let the nodes at which voltage is V1, V2, and Vs2 be 1,2 and 3 respectively.
