SECTION I: DIRECT METHODS IN SOLVING SYSTEMS OF LINEAR EQUATIONS
1. Find the solution of the system of linear
equation using GAUSS-JORDAN ELIMINATION. If the results are not reducible to
fractions, write the values up to 6 decimal places.
2. Solve the same system using Cramer's Rule.
The Augmented matrix is as follows:

in equation form
3w + 2x - 8y - z = -5
Ow + 9x + 4y +3z = 4
- 13w + 2x + 6y +z = -7
- 2w + 3x + 2y + 10z = 0
SECTION II : ITERATIVE METHODS IN SOLVING SYSTEMS OF LINEAR EQUATIONS
1. Find the solution of the system of linear
equation using JACOBI ITERATION. STOP at the 5th Iteration. Compute the
ABSOLUTE ERROR for each iteration. Show the working equation and write the
solution for each iteration very clearly. If the results are not reducible to fractions,
write the values up to 6 decimal places.
2. Find the solution of the system of linear
equation using GAUSS-SEIDEL ITERATION. STOP at the 5th Iteration. Compute the
ABSOLUTE ERROR for each iteration. Show the working equation and write the
solution for each iteration very clearly. If the results are not reducible to fractions,
write the values up to 6 decimal places.
