Vout = 6 ( V1 - V2 )

This circuit represents a cascade op-amps that will perform an output voltage which is equal to the difference between V1 and V2 then will mulitply by 6. Vout = 6 * ( V1 - V2 ). Hint: the output Voltage will not exceed the DC power supply voltages which is either +15V or -15V.
