Solve for the voltage v_o in each of the following circuits. Assume that the following:

represents a circuit whose Thévenin equivalent voltage and resistance are V_{T} and R_{T}, respectively, where V_T is open-circuit voltage measured from the + terminal to the - terminal.

Make the ideal op-amp assumption, and enter your answer as a simple Python expression in terms of V_T (all caps), R_T (all caps), and any other voltages or resistances necessary from the circuit (e.g., V_1, R_1, etc).

1) Circuit 1

2) Circuit 2
