If this is the right solution for this but I consider the the binary zeros on the above figure as active so it will be:.
-5(1/2^2 + 1/2^3) = -1.875.
-5(1/2^2 + 1/2^3) = -1.875.

Rf is 30k. Its was shown.

Rf(value) is not shown in the figure?

How Vin=(v/8)+(v/16)? Please explain.

Here Rf=30k, R=15k.
Vout=-(Rf/R)*Vin.
Vin =(v/8)+(v/16)
=5/8+5/16
=0.9375 volt.
Vout=-(30/15)*0.9375
=-1.875 volt.
Vout=-(Rf/R)*Vin.
Vin =(v/8)+(v/16)
=5/8+5/16
=0.9375 volt.
Vout=-(30/15)*0.9375
=-1.875 volt.
