I have a problem with solving the system of nonlinear equations, I use FindRoot but it produces an incorrect solution. In attached file you can see how I create this system of equation and how I try to solve it. In the first area highlighted in red I use loop Do, and solve the whole system. As you can see by the example of Ue9 (It should equal 2.5) the answer is incorrect. But in the second highlighted area I solve only two equations from the original system and the answer is correct for both variables at every iteration.
Please help me to obtain correct solution of the whole system
Thanks in advance!
