Linear Algebra. All systems will be solved by performing elementary row operations on an augmented matrix until it is transform into REF. Consider the following system: X1-X2-X3=1 , X1 X3=2 , X2 2X3=1 a) "Solve" the system by Gaussian elimination method and "perform" "each" elementary row operations on augmented matrix until it is transform into Reduced Echelon Form. b) Describe the system "Graphically" "sketch" and Graphically sketch your solution
A. Find the Reduced Echelon Form
B. Determine the system solution
C. Identify the elementary row operations
D. Analyze the system graphically
