I solved symbolic system of linear equation (ten equations, ten variables)and the "Solve" command gave me the solution, but if I want a particular root (not all of them) to put into another expression how should I manage...?
Double brackets did no help... it said:
Part::partw: Part 4 of (<<1>>) does not exist..
But I have 10 solutions... and I wanted only the 4th root as an input into some other place
Would you pls advise
