quick question if i have the matrix; (R represents a specific row)
1 1 3 -3 0
0 2 1 -3 3
0 -1 -1 2 -1
R3+R2 -->R2
1 1 3 -3 0
0 1 0 -1 2
0 -1 -1 2 -1
and then R2+R3 -->R3
1 1 3 -3 0
0 1 0 -1 2
0 0 -1 1 1
is there anything wrong with my adding of rows or what not? I'm really just second guessing if i can add a lower row to a higher row. thanks.
