Question: (a) Using the method of Gaussian elimination, find the solution of the equation Hence evaluate the determinant of the matrix in the equation. (b) Solve

(a) Using the method of Gaussian elimination, find the solution of the equation

12 24 2 8x 7 13 25x 159X3 -1 2 1 11 24 1 X 19 57 16 52

Hence evaluate the determinant of the matrix in the equation.

(b) Solve by the method of Gaussian elimination

1 1 2 -1 1 -1 3 3 3 -3 3 0 23-12X4 13 x 0X3 || 11 M
