Question 770379: Suppose that you are solving a system of three linear equations and have evaluated D,Dx,Dy, and Dz. Under what conditions does Cramers rule not apply?
A)Dx=0,Dy=0,orDz=0
B)D=0
C)Dx=0
D)D=0;and either Dx=0, Dy=0, or Dz=0

You can put this solution on YOUR website!
x%22%22=%22%22D%5Bx%5D%2FD, y%22%22=%22%22D%5By%5D%2FD, z%22%22=%22%22D%5Bz%5D%2FD

Since we can't divide by 0, D cannot = 0.

Choice B)
