1. Please refer to attached image.
2. The attempt at a solution.
I noted that Vb was grounded and would therefore be equal to 0 and because one of the two op-amp rules states that Va = Vb, both will be equal to 0.
I wrote an equation at node Va:
[Va - Vin]/R1 + [Va - Vout]/R2 = 0
Because Va is 0, the equation simply became:
-Vin/R1 - Vout/R2 = 0
And plugging in the given values for part (a), I acquired - 5V. I'm not sure if this is correct or not as the book does not have a solution manual available yet.
