Question

Given the system of equations:

2x – y = –2
x = 14 + 2y

What is the value of the system determinant?
What is the value of the y−determinant?
What is the value of the x−determinant?
What is the solution to the system of equations?

Answer 1

I love these...

Answer 2

So would the system determinate be the first matrix?

Answer 3

Yes I have not heard that term before, but by the context it must be correct.

Answer 4

*Determinant, Sorry I mispelled it.

Answer 5

For the first matrix, The solution should be -3 if I am correct.

Answer 6

Yes, -3 is correct.

I will show you the y−determinant, but will expect you to do the x−determinant

So for the y−determinant just substitute the y values with equality values....
