I need help finding the thevenin equivalent voltage for the following network:

i did source transformations so that i could analyze it using the node voltage method.

my equations are:

I

(a) v

2v

(b) v

2v

when i simplify (by substituting v

v

however, the answer should be

v

help please! thanks.

i did source transformations so that i could analyze it using the node voltage method.

my equations are:

I

_{1}= v_{1}(a) v

_{x}+ v_{x}- v_{T}= v_{1}+ av_{1}- bv_{1}2v

_{x}- v_{T}= v_{1}+ av_{1}- bv_{1}(b) v

_{T}- v_{x}+ v_{T}= bv_{1}2v

_{T}- v_{x}= bv_{1}when i simplify (by substituting v

_{x}), i getv

_{T}= v_{1}/3(a + b + 1)however, the answer should be

v

_{T}= v_{1}/2(a + b + 1 - ab)help please! thanks.
