I'm totally lost.
[-18 8 -11] = [-9 8 -8]-3x
I just tried solving it backwards.
[-27 0 -19] = -3x
divide by -3
[9 0 19/3] = x
Is that right?
How come the equation turned into [-18 8 -11] - [-9 8 -8] = [-9 0 -3]
but then you still put -27. Wouldn't -18 - -9 be -9?
I put Antarctica because I hate putting information online
Never mind. I looked at my post while I typed this so I was thinking you put -27.
My bad. I get it now. Thanks/.
