syms y
eq ='(y/lo)-(y/lo*lo)*(lo-y)*(log(lo-y)-log(y))-y(lo-y)*k1-k4*(k2+k3*((rc^2-y^2)/(rc^2-y^2)))^-1==0'
solve(eq,y)
when I run it I got following message
Warning: Explicit solution could not be found. > In solve at 169 In sym_1 at 6
ans =
[ empty sym]

By the way: after you substitute in the values from your other posting, there will be 10 roots, 2 of which will be real-valued.
