2x - y = 5 x + 3y = 7 what is the value of the system determinant?

 The required value of the system determinant is 7.

Step-by-step explanation:  We are given to find the value of the system determinant for the following system of linear equations :

We know that

the first column of the system determinant contains the coefficients of the unknown variable x and the second column contains the coefficients of the unknown variable y.

So, the system determinant can be written as

Thus, the required value of the system determinant is 7.
