Since x2 now is a basic variable, proper form from Gaussian elimination is restored by dividing Eq. (2) by 4, adding 2 times this new Eq. (2) to Eq. (0), and subtracting 2 times this new Eq. (2) from Eq. (1). This yields the following system of equations: (0) Z - 0.5x1 – x3 – 0.5x5 = 6

THE GOAL: We will use Gaussian Elimination to get A to the identity matrix (ones on the main diagonal, zeros elsewhere). We will keep track of the Gaussian Elimination by acting on the Identity matrix. Step 1: Write the matrix A followed by the identity: (1 2) (1 0) (3 5) (0 1)

When n is small (, say) a direct or one-step method is used. For larger systems, iterative methods are preferred. 2. Gaussian Elimination. In a one-step approach, we seek to evaluate the inverse of the matrix. The solution is obtained by carrying out the matrix multiplication . a. Elimination. You may have seen this in high school algebra.
