Solver equation solving

[kovacsak]

I try to solve equation above use of Solver:

=B4*(B1+B5)*EXP(-B1*8*B4)

I have typed values of B4, B5 - these are a and b parameters - and after that using Solver.

How to solve an equation with only one side?

I try to solve equation above use of Solver:

Ok, so what happened?

=B4*(B1+B5)*EXP(-B1*8*B4)

I have typed values of B4, B5 - these are a and b parameters - and after that using Solver.

I seem to recall that the parameters need to be independent. Yet both B1 and B4 are involved in both parameters.

This seems suspicious to me but I don't understand well enough to say for sure.
