s1 = solve(eq,ss)
The result is
ss = **rhs**
By setting all other variables in the right-hand side of the equation, I can retrieve a value using, among other things,
print **rhs**
or
N(**rhs**),
but when I try
N(ss)
I get the error message "cannot evaluate symbolic expression numerically". How can I evaluate the left-hand side as if it were the right-hand side?
