Kirkhoff current law on two nodes

Hello everyone,

Can anybody help me with the balance of the currents on the nodes A and B of the attached picture?
Here is what I obtained:

At node A:
0.8 + V2/10 = 0.15 + V1/7.5 + i(B)
At node B:
i(B) + V3/10 = 0.8

The issue is that considering the balance like this, 0.8 cancels (by substituting i(B) from the second equation to the first one). Where is the mistake? Could anybody help me, please? Thanks a lot in advance
