Given augmented matrix [A|0]: -->RREF -->x=?
I started with:
|0 1 0|0|
|0-3 1|0|
|0 0 2|0|
--->RREF--->
|0 1 0|0|
|0 0 1|0|
|0 0 0|0|
The RREF is correct according to solution manual, but
the solution manual says that the vector x =
|1|
|0|
|0|
I think I understand why x_3 and x_2 =0, But I don't understand why x_1 =1.
