Question
Please solve this system of linear equations.  
-4x-2y+z=-19
-6x+2y-6z=-8
-4x+2y-5z=-6

Answer
I get no solution since after reducing the 1st equation to x and eliminating it from rows 2 and 3 and then reducing the coefficient on the y to 1 in the 2nd equation and subtract off the appropriate values from equation 1 and 3, the third equation is full of zero coefficients with a -3.4 on the right hand side.
