Question 991010
.
You are given the system


{{{system(3x-2y+4z=1,
x+y-2z=3,
2x-3y+6z= 8)}}}.


It has no solution.


Indeed, notice that the third row of coefficients is the difference between the first row and the second row. 


In the same time, the right side of the third equation is not that difference.
