A network contains a total of 12 components and seven nodes

A network contains a total of 12 components and seven nodes. Among the components are 2 independent voltage sources, 1 dependent voltage source, 2 independent current sources, and seven resistors. How many equations and unknowns are there in a nodal (node-to-reference voltage; analysis of this network?

1.one node is ground so remaining nodes are 6 nodes .

so 6 kcl equations will come and 6 unknowns will come .
