### Orthogonal Projection of Vector v on the Solution Space of Ax = 0

To find the orthogonal projection of the vector **v** onto the solution space of the linear system **Ax = 0**, we start with the given data:

\[
\mathbf{v} = (5, 6, 7, 2)
\]

\[
A = \begin{bmatrix}
1 & 1 & 1 & 0 \\
0 & 2 & 1 & 1 \\
\end{bmatrix}
\]

Our task is to project the vector **v** onto the subspace spanned by the solutions of the homogeneous equation **Ax = 0**. This often involves several linear algebra techniques including the calculation of orthogonal complements, using projections, and null spaces.
