i put them into a matrix system

1 1 2

2 -1 1

1 -2 -1

now after performing elementart operations i get

1 1 2

0 -3 -3

0 -3 -3

so since R3 and R2 are the same, dimV=2, my question is if i am asked to give a basis, should i give ( 1 1 2) (0 -3 -3) or should i return to the original vectors given and answer (1 1 2 ) (2 -1 1) or perhaps something else,, is ther a more correct answer if i am asked to give a basis
