**Problem Statement:**

Find all special solutions to the system \( Ax = 0 \) where

\[ 
A = \begin{bmatrix} 
2 & 4 & 1 & 8 & 3 & 1 & 5 \\ 
2 & 4 & 1 & 8 & 3 & 1 & 7 \\ 
2 & 4 & 1 & 8 & 0 & 0 & 6 \\ 
2 & 4 & 1 & 8 & 5 & 0 & 1 \\ 
2 & 4 & 1 & 8 & 7 & 0 & 1 
\end{bmatrix}.
\]

Write down the general solution for this system.

**Instructions for Student:**

1. Begin by setting up the augmented matrix representing the linear system \( Ax = 0 \).
2. Use Gaussian elimination or another row reduction method to put the matrix in row echelon form.
3. Identify the leading variables and free variables from the row echelon form of the matrix.
4. Express the leading variables in terms of the free variables to find the special solutions.
5. Define the general solution of the system as a linear combination of these special solutions.
