ANSWER:

Step 1 of 4

The following are given by the question:

Voltages

                                           

                                         

The voltage at non inverting terminal is equal to the inverting terminal of the op-amp.

                                                                       

The voltages at non-inverting terminal

                                                                        

The voltages at inverting terminal
