# need some help with OP-AMP problems

**The problem statement, all variables and given/known data**

here is the image

the question is to find the A at Vo1 and Vo2

**The attempt at a solution**

I don’t know how to calculate A at Vo1

but at Vo2, what I need to do is just

A= 1 + R/R

is that right?

At Vo1, what I think is only A= 4R/R

but is that right?
