- A$\big[-1,\infty\big]$
- ✓$(1,\infty)$
- C$(\infty,\infty)$
- D$(\infty,1)$
✓
Answer
Correct option: B.
$(1,\infty)$
Given, $2\text{x}+1>3$
$\Rightarrow2\text{x}>3-1$
$\Rightarrow2\text{x}>2$
$\Rightarrow\text{x}>1$
$\Rightarrow\text{x}\in(1,\infty)$
$\Rightarrow2\text{x}>3-1$
$\Rightarrow2\text{x}>2$
$\Rightarrow\text{x}>1$
$\Rightarrow\text{x}\in(1,\infty)$
