The augmented matrix of a system of three equations
with three unknowns is row equivalent to the following matrix
\(A'\). Find
the solution of the system.
\[
A' = \left(\begin{array}{ccc|c}
-1 & -6 & 1 &-20\\
0 & 5 & 4 & -12\\
0 & 0 & 0 & -8
\end{array}\right)
\]
no solution
\(\left [-\frac{172}
{5} ;-\frac{12}
{5} ;0\right ]\)
\([-12t;4t;-8t],\ t\in \mathbb{R}\)
\(\left [-12;4;-8\right ]\)
