Solve the set of equations ([a] [x] = [y]) given by the augmented matrix

A=[-2 4 1 2; 5 1 3 10; -6 7 0 9]

for x using the elimination method such that an upper or lower triangular matrix is obtained using any of the diagonals. Compare your results with those of the regular Gauss elimination method.

Solve the set of equations ([a] [x] = [y]) given by the augmented matrix

A=[-2 4 1 2; 5 1 3 10; -6 7 0 9 ]

for x using the inverse method. First find the inverse of [a] using the Gauss-Jordan method, then solve for x using x = [a]^-1y
