reduced augmented
The following matrix is a reduced augmented matrix obtained from a system of equations.
1 0 0 3 / 6
0 1 0 5 / 4
0 0 0 0 / -2
0 0 0 0 / 0
My answer is infinite based on the non-numbers in the matrix, thanks for looking this one over.

Since the equation equivalent to the third line of this matrix is:

$0.w+0.x+0.y+0.z=-2$

the system is inconsistent, and cannot have any solutions.

thank you
Thats what I thought but wasn't sure of that answer.
