Write the node equations and solve the resulting system of linear equations. You do know how to write node equations - right?

What techniques are you expected to use?

What techniques do you know?

The notion of a node voltage only has meaning if there is a defined reference. So your first step is to define that reference. Pick one of the nodes and call it 0 V. There's a fairly obvious candidate, but the fact is that you have four possible options and, at the end of the day, the choice is arbitrary.

No sorry, I'm new to circuitry
