Answer 1

$\begin{cases}2,8x-17>0,3x-4,5\\12,3x-16,6\leq7,1x+19,8\end{cases}\Rightarrow\begin{cases}2,8x-0,3x>17-4,5\\12,3x-7,1x\leq19,8+16,6\end{cases}\Rightarrow\\\Rightarrow\begin{cases}2,5x>12,5\\5,2x\leq36,4\end{cases}\Rightarrow\begin{cases}x>5\\x\leq7\end{cases}\Rightarrow x\in(5;\;7]$

Целые x - 6 и 7.
