Hello,

I have a linear equation with eight variables and when I use my HP calculator i can enter any seven of these variables to then be given the 8th as an answer.

My question is, is this possible in Excel, I have tried searching and using the solver but this restricts me - or so it seems - to one answer as in i need to have seven solvers running.

(((1/(1+(R1%*D)/B1))/(1/(1+(R2*D)/B2))*S)-S)*Coff

Many Thanks

Pete
