Answer:
Question 1:
For this case we have the following system of equations:
2x - y = 5
x + 3y = 7
We rewrite the system of equations of the form:
Ax = b
Where,
A: coefficient matrix.
x: incognita vector
b: vector solution.
We have then:
We look for the determinant of A.
We have then:
Answer:
the value of the system determinant is:
A = 7
