Answer 1

Explicație pas cu pas:

$\begin{cases}x - 5 \leqslant 4x - 17 \\2x - 15 > 1 \end{cases} \iff \begin{cases}17 - 5 \leqslant 4x - x \\2x > 1 + 15 \end{cases}$

$\begin{cases}3x \geqslant 12 \\2x > 16 \end{cases} \iff \begin{cases}x \geqslant 4 \\x > 8 \end{cases}$

$\begin{cases}x \in \Big[4 ; +\infty \Big) \\x \in \Big(8 ; +\infty \Big) \end{cases} \implies x \in \Big(8 ; +\infty \Big)$
