Hey Rohit,
Thanks for your message. I've solved the problem.
But anyhow I get an error
RowReduce::luc: Result for RowReduce of badly conditioned matrix {{0.,0.,0.,0.,0.,1.,-4.65646,0.00009025,0.},{0.,0.,0.,0.,0.,0.,105.263,0.019,0.},<<5>>,{5.6108710^7,0.,-5416.31,4.0134910^11,-3.67011*10^7,0.,0.,0.,-1170.}} may contain significant numerical errors.
Could you please help me if you know it?
