Now we need to write the Node-Voltage Method Equations. There will be
six equations plus two more for the dependent source variables iX and vX. We will
take them alphabetically.
For node A, we have two voltage sources connected. The vS1 source has a
series element that we can use to express a current in that branch. However, the vS2
source is between two non-reference essential nodes. We will need a supernode
equation and a constraint equation. The supernode is drawn with a dashed red line
in the circuit diagram that follows.
