Question

solve using Gauss-Jordan elimination

Given the equations below
6v +-8w+-1x + 5y +-5z = 12
-1v+-2w + -9x + 8y + 6z = -7
-5v +-5w+ 6x + 1y +-2z = 18
-1v + -4w + 3x + -1y+-1z = 25
-2v +-8w+-9x + 6y + 8z = -3
The final augmented matrix using Gauss Elimination Method would look like this:

Solve for R if
R = a11 + f22 + g33 + h44 + i55
