find the system determinant of the given matrix.
-30 will be the determinant.
We have to find the system determinant of the given matrix
Determinant will be = 2(-9) - (4 × 3)
= -18 -12
Therefore, as per given options by you in the comments.
option A is the answer.
In the case of a 2 × 2 matrix the determinant may be defined as:
|A| = = ad-bc
Given in the question a matrix
(-30)(30) - (-6)(6)
-900 + 36
Option A: -30
