Answer to Problem 22RE
The solution of the system of equations is
Explanation of Solution
Given information:
The following system linear equation as given below,
Formula used:
The Gaussian elimination with back substitution is used.
Calculation:
The augmented matrix is:
To apply Gaussian elimination with back substitution, this has to be converted to the row-echelon form by the elementary row transformations:
So, the system of equation becomes:
The third equation gives:
Putting this value in the second equation:
Putting these values in the first equation:
Hence, the solution of the system of equations is
Conclusion:
The solution of the system of equations is
