thanks a lot, it starts to work now. Can you tell me, how can
I extract the right hand side of one of those two solutions? I mean:

B_result:solve(eq4,B);

produces a lenghty:

[B= ...., B= .....]

And so I want to assign:

B1: right_hand_side_of(B_result[1])

Which doesn't work of course, so I do:

B1: B_result[1]

And it becomes:

B1: B=.......

But I want only the right hand side:

B1: .......

how do I do that?
