Another approach would be to convert the left-hand part of the circuit comprising the V1 source and the resistors R1 & R2 to a Thevenin equivalent. The values appear to have been chosen with that in mind.

The subsequent analysis then becomes relatively straightforward.

You also avoid the supernode.
