Hi, it is the pre-lab working. Please help me do that, i will rate up immediately whenever i have the answer. Thanks so much in advance.

R R, 6 6 3 + R, + Vout Design the inverting summing amplifier in Fig above by choosing resistor values R1, R2, and Rf to meet the following specifications: the voltage gain Avi= Vout/V1 = -10.85. the voltage gain A v2= Vout/V2= -0.667. the values of R1, R2, and Rfmust not be less than 4.7 KQ. The available resistors are listed in Table I. Use resistor combinations if necessary.
