i need to assign the 2 nodes next to Va as V1 and V2?

then he two nodes will have the same voltage
Va on both the nodes

yea i think i got it, its very close to my experimental value.

It's easy, summing currents leaving from super node ( the branch with voltage Va)
\[\frac{V_a-E_1}{R_1}+\frac{V_a-0}{R2}+\frac{V_a-0}{R3}+\frac{V_a-E2}{R4}=0\]
