5. SOLVING SYSTEMS OF LINEAR EQUATIONS:
Consider the following linear system of equations. (Note that this is a system of
three equations in three variables).
5x +5y-7z 3
2y - 5z = 1
4.x + 3z = 3
(a) Set up the augmented matrix corresponding to the system above and per-
form at least four iterations of the Gauss Jordan Reduction algorithm to the
augmented matrix, without using the calculator.
(b) Using your calculator, find the reduced row echelon form of the coefficient
matrix for the system above.
(c) Use the reduced row echelon form to read off the solution(s) of the linear
system.
Calculator Tips: Click here for a video with instructions on finding the row
echelon and reduced row echelon form of a matrix. The textbook also contains
instructions on pg. 658.
