Using a Graphing Utility In Exercises 97-100, use the matrix capabilities of a graphing utility to reduce the augmented matrix corresponding to the system of equations and solve the system.

\(\left\{\begin{aligned} 3 x-y+5 z-2 w &=-44 \\ x+6 y+4 z-w &=1 \\ 5 x-y+z+3 w &=-15 \\ 4 y-z-8 w &=58 \end{aligned}\right.\)

Text Transcription:

{_4y - z - 8w = 58  ^5x - y + z + 3w = -15  ^^x + 6y + 4z  - w = 1  ^^^3x - y + 5z - 2w = -44
