There is no other voltage,

So, vR2 = Va = 4.18A.

Here, we can use superposition to solve it.

We can also find through voltage divider formula i.e. [37/ (37+68) ]*12 = 4.22v almost near tp 4.18v.

12-Va/68 - Va/37 - (Va-4)/90 =0

12/68 + 4/90 = Va(1/68 + 1/37 + 1/90)

Va ( 323.41 )=1352
Va=4.18

For the node analysis the value of node volage is equal to 4.184 volt and the voltage drop across r2 is 4.184 volt.
