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) Write the system in the form Ax=b,
b) Identify A, x, and b,
c) "Solve" the system
d) Describe "graphically" the system and your answer to part c.
a) Yes
b) No
