Linear Independence and Combinations

In the field of mathematics, linear independence is a term that describes vectors that cannot be expressed as a linear combination of other vectors. On the other hand, linear combinations involve the process of multiplying vectors by specific scalars and then adding or subtracting the results. These principles are vital in understanding vector spaces and systems of linear equations.

to $A$, and use $B$ to give all solutions of the system of linear equations. \[ A=\left[\begin{array}{rrrr} -1 & 1 & 1 & -5 \\ -1 & 3 & -9 & -19 \\ 7 & -2 & -32 & 0 \end{array}\right], \quad B=\left[\begin{array}{rrrr} 1 & 0 & -6 & -2 \\ 0 & 1 & -5 & -7 \\ 0 & 0 & 0 & 0 \end{array}\right] \]
