Find The Thevenins Equivalent of the circuit shown .

at the terminal a and b i think

2. Relevant equations

Vth = Rth(Ith)

V= IR

3. The attempt at a solution

For Vth

i tried using Nodal Analysis Having 4 Node Voltages

but i dont know if the 5 ohms resistor and 8 ohms resistor is having flow of current in there?

For Rth

the Current source is change into open ckt.

then solve by having 40 and 20 in series then parallel in 10 ohms

therefor [(40+20)x10]/70 + 45 + 5 + 8 = 78 ohms = Rth

So im wondering how should i get the Vth now,,

And is Vth = Va + 35V and Vth = Vb +15 V ? or I = (Va + 35 - Vth) / 5 ohms
