khatus:
Can anybody solve the following problem?? and posts each steps of solution if possible

khatus:


STEP-1: At first i apply KCL at node x. which give me



Then how i can proceed further??

IconicPCB:
Vc = 9- Rc*Ic
IC = 45 * Ib
Ib = Ira - Irb

Ira= (Vin-0.7)/Ra
Irb = 0.7/Rb

khatus:
So the node voltage

Vx = VBE (base emitter voltage) ??

bson:

Well, yeah.  The only thing between it and ground is B-E, which is 0.7V.
