For op-amp 1: Vo = -(rf/r1)v1=-(500/250)*v1=-2v1.
For op-amp 2: Vo' = -rf(-2v1/100+v2/50).
= 500*2v1/100-500/50.
= 10v1-10v2.
= -10(v2-v1).
For op-amp 2: Vo' = -rf(-2v1/100+v2/50).
= 500*2v1/100-500/50.
= 10v1-10v2.
= -10(v2-v1).

For op amp 1:
Vo= -(Rf/R1)v1,
Vo= (-500/250)v1 = -2v1.
for Op Amp 2:
Vo'=-rf((Vo/R2)+(Vs2/Rs2)),
Vo'= -500 ((-2V1/100)+(V2/50)),
Vo' = 10v1-10v2,
Ans: 10(V2-V1).
Vo= -(Rf/R1)v1,
Vo= (-500/250)v1 = -2v1.
for Op Amp 2:
Vo'=-rf((Vo/R2)+(Vs2/Rs2)),
Vo'= -500 ((-2V1/100)+(V2/50)),
Vo' = 10v1-10v2,
Ans: 10(V2-V1).
