\(\begin{array}{l}\left\{ \begin{array}{l}\;{d_1}:2x + 3y - 19 = 0\\\;{d_2}:\left\{ {\begin{array}{*{20}{c}}{x = 22 + 2t}\\{y = 55 + 5t}\end{array}} \right.\end{array} \right.\\{d_1} \cap {d_2} \Rightarrow 2\left( {22 + 2t} \right) + 3\left( {55 + 5t} \right) - 19 = 0\\ \Leftrightarrow t = - 10\\ \Rightarrow \left\{ \begin{array}{l}x = 2\\y = 5\end{array} \right..\end{array}\)
