Quiz 8.6 		Question: Solve the following system of linear equations. If there are infinitely many solutions, enter redundant. If there is no solution, enter no solution.
6x+y–5z = 4
5x+7y+2z = 28
4x–y–5z = –4

 		 
     
  Variation: Solve the following system of linear equations. If there are infinitely many solutions, enter redundant. If there is no solution, enter no solution.
x–4y+5z = 15
x+5y–4z = –13
8x+5y+3z = –34
