Given:
The system of equations is:
The given matrices are , , .
To find:
The correct names for the given matrices.
Solution:
We have,
Here, coefficients of x are 1 and 1 respectively, the coefficients of y are 3 and -3 respectively and constant terms are 5 and -1 respectively.
In the x-determinant, the coefficients of x are in the first column and the constant terms are in the second column. So, the x-determinant is:
In the y-determinant, the constant terms are in the first column and the coefficients of y are in the second column. So, the y-determinant is:
In the system determinant, the coefficients of x are in the first column and the coefficients of y are in the second column. So, the system determinant is:
Therefore, the first matrix is y-determinant, second matrix is x-determinant and the third matrix is the system determinant.
