Opamp Question not clear with currents

[Vihaan]

I am unclear of how to mark the currents, i have written the equations the problem is 4 unkowns and 3 equations, how do i solve?

You have the necessary number of equations.

Use KCL at nodes A, B, C and D and also use the fact that C = D through the opamp action.
This gives you 5 equations and 5 unknowns (A, B, C, D and Vout).

Example KCL equation for node A:

-5.5ma + (B-A)/22k + (D-A)/22k = 0

Ok, thank you very much the below equations considering A,B,C,D and C = D
The updated solution is i have attached, the voltages are very high the opamp will saturate to 9V.
VA = 821.33V, VB = 902V, VD=861V, VC = 861V, Vout = 1723V.
I made LTspice and it matches with the results.

You do realize that those voltages are impossible, yes?

Sorry I can't help you here—this stuff is all above my pay grade—but I do recognize out-of-bounds conditions when I see them.

Also, beware (or more correctly, be wary) of simulations.
