hello guys can you help me to produce the thevenin's equivalent circuit of this circuit
View attachment Doc1.doc
kindly help me please.....

 

Sure. Post a pic of the circuit rather than a .doc file. I will reply later(when I boot into xp which has ms office)

 

thanks.....but it's too large as a pic..... i will try to post it.... please help to solve it in superposition....

I do not see how this pictures can be to large. Then posting pictures. Most of us use the png format, or PDF. You can save pictures in PNG format using MS Paint. But well here is the pictures.

 

Across which two points we need to find the thevenin equivalent circuit? The diagrams doesn't have the points. And I guess the two diagrams are separate problems.

For the second diagram I assumed the thevenin equivalent is across the 70 ohm resistor(marked Vx) and found the
Vth=-27.5 V
Rth=23.5714
