The given matrix form of system of three linear equations in three unknown is,
AX=D
The system of linear equations will be inconsistent if rank of A is not equal to the rank of AD and rank of AD is greater than rank of A
since, the rank of augmented matrix is greater than or equal to the rank of coefficient matrix.
Thus,

rank‌of‌A

rank‌of‌AD

<1
