PLEASE HELP on a TEST 2x - y = 5
X+ 3y = 7
What is the value of the y-determinant
7
22
9 ​

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:

the value of the system determinant is:

A = 7

Step-by-step explanation:

For the first one it's Using the slope-intercept form, the slope is 2 .

large=it holds more then the small

small=it holds less then the large
