Which determinants can be used to solve for x and y in the system of linear equations below?

The determinants can be used to solve for x and y in the system of linear equations below are:

Step-by-step explanation:

We are given a system of linear equations as:

and      

Hence, we can form a matrix with the help of these equations as:

where A is a matrix formed by the coefficients of x and y and is a 2×2 matrix.

and b is a matrix formed by the term after equality and is a 2×1 matrix.

Hence, we have:

As we know that:
