What is the value of   a24

 

Note: Decimal values should be approximated up to 4 decimal places.

Consider the system of equations:
-2x + z = -4
-x + 2y + z = -50
5x-у + z%3D-26
with the corresponding matrix equation
-2 0 1
-4
-1 7 1
уЕ -50
y
5 -1 1
-26
and with the augmented matrix
[ -2 0 1 -4
-1 7 1 -50
5 -1 1 -26
Using the Gaussian method, the augmented matrix can be transformed into
-2 0
1 -4
0 а22 а2з а24
