Dané sú mimobežné priamky $a$ a $b$. \begin{align*} a\colon x&= -1-2t, & b\colon x&= 1-3s, \\ y&= -2+3t, & y&=2s, \\ z&= -4+2t;\ t\in\mathbb{R}, & z&= 2-2s;\ s\in\mathbb{R}. \end{align*} Nájdite parametrické vyjadrenie priamky $p$, ktorá pretína obe priamky $a$ a $b$ a leží v rovine $2x+3y-z-8=0$.
$\begin{aligned} p\colon x&=-9+r, \\ y&=10+r, \\ z&=4+5r;\ r\in\mathbb{R} \end{aligned}$
