58. Consider the circuit of figure P6.58. Suppose v = 36 V and v,2 0. Without writing and solving simultaneous equa- tions, find va by utilizing the results of problem 6.57 and all the theorems studied so far. Hint: Use the following decom- position: [36 0] - [,1, ,2] = [18 18]+[18 -18], Now find the contribution to vg ue to [18 18] and then the contribution to y, due to [18 -18] and %3D apply superposition. 120 10 lieure Ph.58
