Step-by-step solution

2 steps

Determine the output voltages of the first two op-amps.
The first two op-amps are configured as voltage followers. For an ideal voltage follower, the output voltage is equal to the input voltage.
For the top op-amp:
$V_{out1} = V_1 = 3 \text{ V}$
For the bottom op-amp:
$V_{out2} = V_2 = 1 \text{ V}$
Calculate the voltages $V_A$ and $V_B$ using the voltage divider rule.
The resistors between $V_{out1}$ and $V_{out2}$ are $R_1 = 5 \text
