Jika x→=3u→−v→+w→\overrightarrow{x}=3\overrightarrow{u}-\overrightarrow{v}+\overrightarrow{w}x=3u−v+w, y→=u→+2v→−2w→\overrightarrow{y}=\overrightarrow{u}+2\overrightarrow{v}-2\overrightarrow{w}y=u+2v−2w, dan z→=2u→−3v→+4w→\overrightarrow{z}=2\overrightarrow{u}-3\overrightarrow{v}+4\overrightarrow{w}z=2u−3v+4w, maka hasil x→+2y→−z→\overrightarrow{x}+2\overrightarrow{y}-\overrightarrow{z}x+2y−z adalah ....
3u→−6v→+7w→3\overrightarrow{u}-6\overrightarrow{v}+7\overrightarrow{w}3u−6v+7w
3u→+6v→−7w→3\overrightarrow{u}+6\overrightarrow{v}-7\overrightarrow{w}3u+6v−7w
−3u→+6v→+7w→-3\overrightarrow{u}+6\overrightarrow{v}+7\overrightarrow{w}−3u+6v+7w
3u→−6v→−7w→3\overrightarrow{u}-6\overrightarrow{v}-7\overrightarrow{w}3u−6v−7w
−3u→+6v→−7w→-3\overrightarrow{u}+6\overrightarrow{v}-7\overrightarrow{w}−3u+6v−7w
