I couldn't solve it.
So show us what you tried. We can use that to help guide your approach better. We do not do your work for you here.

Here is how I tried. I don't know how to solve further. I don't know how to calculate the potential difference between those points.

I'm sorry for not understanding how things work here.

I don't know how to find the potential difference between those points. So I can't slove further.

Since you defined ABC as 0 potential, what is the potential at point Y? Recall that you said there is no current through R3.
Using similar reasoning can you find the potential at point X? What do you need to know to calculate the potential at point X?

Note: your current calculation is off by 1,000,000 times. Except for the sign error it's correct.
