	Các bình luận về: 3. 	Cho hai đường thẳng  \(\left( {{d_1}} \right):\,\left\{ \begin{array}{l}x =  &#8211; t\\y = 1\\z = 2 + t\end{array} \right.\) và \(\left( {{d_1}} \right):\,\left\{ \begin{array}{l}x = 2 + t\\y = 1\\z = 1\end{array} \right.\) và điểm \(A\left( {1;\,1;\frac{4}{3}} \right)\). Viết phương trình đường thẳng \(\left( \Delta  \right)\) qua \(A\) sao cho \(\Delta ;\,{d_1};\,{d_2}\) đồng quy.	</title>
