Question
Solve – 8 $\le$ 5x – 3 < 7.
✓
Answer
Given that, – 8 $\le$ 5x –3 < 7
$\Rightarrow$ – 8+3 $\le$ 5x –3+3< 7+3
$\Rightarrow$ –5 $\le$ 5x < 10
$\Rightarrow$ –1 $\le$ x < 2
$\Rightarrow$ x $\in$ [-1,2)
$\Rightarrow$ – 8+3 $\le$ 5x –3+3< 7+3
$\Rightarrow$ –5 $\le$ 5x < 10
$\Rightarrow$ –1 $\le$ x < 2
$\Rightarrow$ x $\in$ [-1,2)
