Use the proportionality property of linear circuits to find the voltage Vx
... Find k by analysis of that circuit. We can then use k to find the output when given any input. So set Vx = 1 V and let the input be unknown. There is no current flowing through either the 22 Ω resistor or the 81 Ω resistor. This means that the voltage across each element is 0V. So we can replace the ...
