Решите неравенство 1) 2

$1) \left \{ {{x+16\ \textgreater \ 0} \atop {x-11\ \textless \ 0}} \right. \Longleftrightarrow \left \{ {{x\ \textgreater \ -16} \atop {x\ \textless \ 11}} \right. \Rightarrow x\in (-16;11)$
$\left \{ {{x+16\ \textless \ 0} \atop {x-11\ \textgreater \ 0}} \right. \Longleftrightarrow \left \{ {{x\ \textless \ -16} \atop {x\ \textgreater \ 11}} \right. \Rightarrow$ решений нет.
Ответ: $x\in (-16;11)$
$2) \left \{ {{x-8\ \textgreater \ 0} \atop {x+4\ \textgreater \ 0}} \right. \Longleftrightarrow \left \{ {{x\ \textgreater \ 8} \atop {x\ \textgreater \ -4}} \right. \Rightarrow x \in (8;+\infty)$
$\left \{ {{x-8\ \textless \ 0} \atop {x+4\ \textless \ 0}} \right. \Longleftrightarrow \left \{ {{x\ \textless \ 8} \atop {x\ \textless \ -4}} \right. \Rightarrow x\in (-\infty;-4)$
Ответ: $x\in (-\infty;-4)\cup(8; +\infty)$
