Thank you for your reply.
I tried this but I got a csv file that contains just this line :
{q1 q2 q3 q4 lamda} /. ans
I tried this also :
Export["data.txt", NSolve[{eq1, eq2, eq3, eq4, eq5}, {q1, q2, q3, q4, lamda}, Reals]]
I got this time a text file contains all results. But for me, I want just the numeric data (just the numbers) without the letters {q1,q2,q3,q4,lamda } and Symbols "->",ie, just the valus of q and lamda.
Best regards.
