Thank you very much for your reply and the link to kit Baum his answer!

my regression could be presented like this:

= equals "is function from"

y1= x1 x2 y2 y3 + e
y2 = x4 x5 x6  y3 +u
y3 = x7 x8 x9 y2 +v
x4= x7 +error
x5=x8 +error
x6=x9 +error

Because E[x4-x9 , e]= 0 

ivreg29 y1 x1 x2  (y2 y3= x4-x9),...

Correct?
