Apply the Partial Pivot Gauss Elimination Method to solve the linear system below. You should only make the necessary line changes for pivoting, without making additional changes. Fill in the first table below with the coefficients and independent terms of the system obtained after all the scaling steps. Note that the table is already partially filled. Also, note that the equations may not be in the same order as they were initially due to pivoting steps. The second table must be filled with the system solution. Perform calculations with 4 decimal places and rounding. Use comma as separator for fractional values (Ex: 3.145 instead of 3.145).
Gauss elimination method states that in order to solve a system of equations we follow the following steps:
1. We write the system in matrix form as Ax=b
2. We make every entry 0 right below the leading entries in every column
3. Now we expand the system and find the values of unknowns.
