design a circuit that solves the following set of equations:
21Xa - 10Xb - 10Xc = 1
-10Xa + 22Xb - 10Xc = -2
-10Xa - 10Xb + 20Xc = 10
to find Xa, Xb, and Xc. Your circuit should consist of only the following elements: one 1 ohm resistor, one 2 ohm resistor, three 10 ohm resistors, three ideal constant voltage sources, and three ideal ammeters, The circuit should be designed such that each ammeter displays one of the values, Xa, Xb, Xc. Draw a diagram of the circuit and indicate the required value of each voltage source.
