Aw yis
take the coefients and put them in rows
![\left[\begin{array}{ccc}4&5&|-7\\3&-6&|24\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%265%26%7C-7%5C%5C3%26-6%26%7C24%5Cend%7Barray%7D%5Cright%5D%20)
divide 2nd row by 3
![\left[\begin{array}{ccc}4&5&|-7\\1&-2&|8\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%265%26%7C-7%5C%5C1%26-2%26%7C8%5Cend%7Barray%7D%5Cright%5D%20)
multiply 2nd row by -4 and add to top one

divide top row by 13

multiply top row by 2 and add to bottom row

Answer:
using the first two equations cancelling the z
-2x-2y-5z=-7
6x+8y+5z=9
4x +6y= 2
using the second and the third equations cancelling the z
6x+8y+5z= 9
-2x-3y-5z= -6
4x +5y = 3
4x + 6y = 2
-4x -5y = -3
y= -1
2x + 2(-1) + 5z = 7
2x - 2 + 5z = 7
2x + 5z = 9
6x + 8(-1) + 5z = 9
6x - 8 + 5z = 9
6x + 5z = 17
-2x - 5z= -9
4x = 8
x = 2
2(2) + 2(-1) + 5z= 7
4 - 2 + 5z = 7
2 + 5z = 7
5z = 5
z = 1
(2, -1, 1)
the answer is a.
