Q:

Draw curcuit by transfer function

Using one operational amplifier, draw the circuit of an amplifier with the following transfer function:
Vo = 6V1 + 3V2 + V3.
Using one operational amplifier, draw the circuit of an amplifier with the following transfer function:
Vo = V1 + 2V2 − 10V

What I have tried:

Can you show the formula? Thank you

A:

\$ V_o = 6V_1 + 3V_2 + V_3= 10\cdot(6V_1 + 3V_2 + V_3)/10 \$
where non-inverting gain = 9+1 and inverting gain =9

Here shown with V1,2,3 with unique values of 0.01,0.10,1.0 to show distinct gains of 6,3,1 with 1.36 V out.
You can do the 2nd one.
