problem

A plane PP is parmeterized by \[\mathbf{v} = \begin{pmatrix} 1 \\ 6 \\ 7 \end{pmatrix} + t \begin{pmatrix} 2 \\ -1 \\ -1 \end{pmatrix} + s \begin{pmatrix} 2 \\ -3 \\ -5 \end{pmatrix},\]and line LL is parameterized by \[\mathbf{w} = \begin{pmatrix} 7 \\ 4 \\ 1 \end{pmatrix} + u \begin{pmatrix} 3 \\ 0 \\ -1 \end{pmatrix}.\]Find the intersection of plane PP and line L.L.
Plain-text mathematical notation (without MathML)
A plane P is parmeterized by
\[\mathbf{v} = \begin{pmatrix} 1 \\ 6 \\ 7 \end{pmatrix} + t \begin{pmatrix} 2 \\ -1 \\ -1 \end{pmatrix} + s \begin{pmatrix} 2 \\ -3 \\ -5 \end{pmatrix},\]and line L is parameterized by
\[\mathbf{w} = \begin{pmatrix} 7 \\ 4 \\ 1 \end{pmatrix} + u \begin{pmatrix} 3 \\ 0 \\ -1 \end{pmatrix}.\]Find the intersection of plane P and line L.
Original LaTeX notation
A plane $P$ is parmeterized by
\[\mathbf{v} = \begin{pmatrix} 1 \\ 6 \\ 7 \end{pmatrix} + t \begin{pmatrix} 2 \\ -1 \\ -1 \end{pmatrix} + s \begin{pmatrix} 2 \\ -3 \\ -5 \end{pmatrix},\]and line $L$ is parameterized by
\[\mathbf{w} = \begin{pmatrix} 7 \\ 4 \\ 1 \end{pmatrix} + u \begin{pmatrix} 3 \\ 0 \\ -1 \end{pmatrix}.\]Find the intersection of plane $P$ and line $L.$
