hii and thank you i simulated this circuit on multisim the first one on the left gives vout across the resistor 1v and the other circuit multiplies it by 2 by the problem i am having is connecting them together

helllo i am having a problem designing this circuit i should use opamps resistors and switched i have a fixed 5v dc input i should get an outpout of -1 -2 -4 -8 -16 the user should choose which one he should use can i get some help please?
