I do have the answers here. They're from the other answer you saw.. Some of the answers are also in the pictures as well. But i'm really sorry, I still haven't figured out 10 yet...

Answer:
Option D
Step-by-step explanation:
We are given the following equations -
It would be best to solve this equation in matrix form. Write down the coefficients of each terms, and reduce to " row echelon form " -
First, I swapped the first and third rows.
Leading coefficient of row 2 canceled.
The start value of row 3 was canceled.
Matrix rows 2 and 3 were swapped.
Leading coefficient in row 3 was canceled.
And at this point, I came to the conclusion that this system of equations had no solutions, considering it reduced to this -
The positioning of the zeros indicated that there was no solution!
