Apply Gaussian Elimination to Systems Without Unique Solutions
Use Gaussian elimination to find the complete solution to the system of equations, or state that none exists.
- \[\begin{array} { l }
x - y + z - w = 10 \\
\quad - 2 x + 3 y + 5 w = - 28 \\
x + 2 y + 8 z + 3 w = - 10 \\
x - 4 y - 6 z - 5 w = 30 \\

• A){ ( - 17 w - 10 , - 13 w - 16,5 w + 4 , w ) }
• B) { ( 3 w - 2 , - 8 w + 3,4 w + 9 , w ) }
• C) { ( 24,10 , - 6 , - 2 ) }
• D) \( \varnothing \)
