Answer:

Determinant of matrix = 12

Step-by-step explanation:

rewrite this system with matrices

[{4   ,   -3]

[8,     -3]]

determinant =   4*(-3)  -  (-3)*8 =  -12 + 24 = 12

are you finding the inverse too?

the  system should look like   A* v  =  C

where matrix A is

[{4   ,   -3]

[8,     -3]]

and  V = [x  , y]  vector

C = [-8, 12]  vector

Answer:

Explanation: When the determinant of the coefficient matrix of a system of linear equations equals zero it means that at least one equation in the system is a scalar multiple of another equation. Hence it is not possible to find the inverse matrix and so the system cannot be solved.
