    I am totally lost about this problem. The circuit layout is the same as the pic just that the3uA is replaced with 27uA and I need to calculate Vout ..

    Are you familiar with the superposition theorem? It reduces the analysis to three simple OpAmps circuits.

    There are a couple of initial assumptions you might also need to make.

    If the op-amp is considered to be ideal. Then ....

    1. The input currents to the op-amp input terminals are zero.
    2. The amplifier output resistance is zero.
    These points will then assist with the analysis.
