In the circuit of Fig. 4-48 remove the 2-A current source and set the other two sources to zero, reducing the circuit to a source-free resistive circuit. Find R, the equivalent resistance seen from terminals CD, and note that the answer is equal to the Thévenin resistance obtained in Problem 4.40.

Data from Problem 4.40

Use the values for V_C and V_o.c. obtained in Problems 4.36 and 4.39 to find the Thévenin equivalent of the circuit of Fig. 4-48 seen by the 2-A current source.

Data from Problem 4.36

In the circuit of Fig. 4-48 write three node equations for nodes A, B, and C, with node D as the reference, and find the node voltages.
