Hello all,

x = [(a-b(1+i)^-n)*y] / [(1-(1+i)^(n-y))/i)+y].

i need to get the reverse formulae for a,b,i,n and y. i need this information urgently. please help.

Thanks in Advance

a and b are straightforward.

It does not appear to be possible to solve explicitly for i and y. I have not proved this, but I cannot see any way to do it.

n can be solved for by first forming a quadratic in :
