X+ y = 12
x - y = 10
what is the value of the x-determinant for the system shown?
a)-22
b)-12
c)-2

Option C is correct

value of the x-determinant for the system is, -2

Step-by-step explanation:

Given the system of equation:

x + y =12

x -y =10

Represents the system of equations in matrix format:

Now, to find the determinant of a matrix.

Formula for the determinant of matrix:

then;

The value of the x-determinant:

Using determinant(D) formula:

Therefore, the value of the x-determinant for the system is, -2
