Question
Solve and graph the solution set of $:2x – 9 < 7$ and $3x + 9 \leq 25, x \in R$
✓
Answer
$2 x-9<7 \text { and } 3 x+9 \leq 25 $
$2 x>16 \text { and } 3 x \leq 16$
$x < 8$ and $x \Leftarrow 5 1/3$
$\therefore$ Solution set $= \{x \Leftarrow 5 1/3, x \in R\}$
The required graph on number line is:
$2 x>16 \text { and } 3 x \leq 16$
$x < 8$ and $x \Leftarrow 5 1/3$
$\therefore$ Solution set $= \{x \Leftarrow 5 1/3, x \in R\}$
The required graph on number line is:
