I got three equations:
l-cm-bn=0
-cl+m-an=0
-bl-am+n=0
In my textbook, its written "eliminating l, m, n we get:"
$$
\begin{vmatrix}
1& -c& -b\\
-c& 1& -a\\
-b& -a& 1\\
\end{vmatrix}=0
$$
but if I take l, m, n as variables and since ##l=\frac{\Delta_1}{\Delta}## (Cramer's rule) and ##\Delta_1=0##, then if ##\Delta=0##,you get an indeterminate form.
Is the expression given in my textbook correct?
