You can put this solution on YOUR website! what is the value of determinent if entries in any two rows of the determinent are crrespondingly proportional
---
That condition implies two equations are actually the same.
So there is an infinite set of solutions.
So, for example, Dx/D = Dx/0
---
So the coefficient determinant is zero.
====================
Another way to look at it:
Using row operations you can create a row with all elements = 0.
Therefore the determinant will be zero.
