The Attempt at a Solution



After having simplified the positive terminal of the op amp, how is this calculated into the overall equation to find v(out)? Also, at the v(out) node, in what respect is the 370Ω resistor and voltage source considered? Would this be a subtraction from (Rf/R1)*v(out) equation?

Can you please post your work? This appears to be a pretty straightforward problem.

Is there a specific equation we use, or do you know what it is called when the voltage source exists at the positive terminal of op amp?

Can someone please provide a little bit of advice or direction on how to solve this. I have simplified the positive terminal of the op amp, and I know that v(out) = A(v(+) - v(-)) ..... but I dont know what to calculate.

-v1(Rf/Rin) = v(out)

23.9mV*(33k/1799.6) = v(out) = 0.4383 V
