in A2. The outcome is shown below. Fig. 3. Step 2 of the LU decomposition method. Finally, we need to eliminate element in row 3 and column 2 of A2(that is, the value in cell G11). This can be achieved by adding (-1) times row 2 of A2 to row 3 of A2 and storing the resulting matrix (with rows 1 and
