You might try nnumeric solutions, if they suffice:
In[1]:=
?NSolve
"NSolve[lhs==rhs, var] gives a list of numerical approximations to the roots
\
of a polynomial equation."
In[2]:=
?FindRoot
"FindRoot[lhs==rhs, {x, x0}] searches for a numerical solution to the \
equation lhs==rhs, starting with x=x0."
