For a constant \( a \), consider

\[
A = \begin{pmatrix} 
0 & a & 0 & 0 & 0 \\
-a & 0 & a & 0 & 0 \\
0 & -a & 0 & a & 0 \\
a & 0 & -a & 0 & a \\
a & a & a & -a & 0 
\end{pmatrix}
\]

Find the nullspace of \( A \). Find the complete solution \( Ax = b \) for \( b = (1, 0, 0, 0, 0) \) or explain why the solution does not exist.
