This is very weird, but I found an inconsistency in the application of Cramer's Rule for a 3x3 simple linear matrix.(adsbygoogle = window.adsbygoogle || []).push({});

1x + 1y + 0z = 3

-1x + 3y + 4z = -3

0x + 4y + 3z = 2

Dz =

1 1 3

-1 3 -3

0 4 2

If you take the determinant across the first row To find Dz, I constantly get -16

If you take the determinant across any other rows or columns, you get the correct Dz = 8

What is going on?????????

Help please.
