3–21 The circuit in Figure P3−21 seems to require two supermeshes since both current sources appear in two meshes. However, sometimes rearranging the circuit diagram will eliminate the need for a supermesh.

(a) Show that supermeshes can be avoided in Figure P3−21 by rearranging the connection of resistor R6.

(b) Formulate mesh-current equations for the modified circuit as redrawn in part (a).

(c) Solve for vx when R1 =R2 =R3 =R4 =1 kΩ, R5 =R6 =

10 kΩ, iS1 = 100 mA, and iS2 = 50 mA.
