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.

126 maybe. sorry

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
