Solve the following 3×3 system of equations by hand using matrices (also known as Gauss- Jordan Elimination).

Solve the following 3×3 system of equations by hand using matrices (also known as Gauss-

Jordan Elimination). That is, transform the augmented matrix into row echelon form (ref –

ones on the diagonal and zeros below the diagonal), change the reduced matrix back into a

system of equations to solve for all the variables. Write your solution as an ordered triple
