Answer 2

$\bf \Large \rightarrow \: \:2x \: + \: 1 \: = \: 3$

$\bf \Large \rightarrow \: \:2x \: = \: 3 \: - \: 1$

$\bf \Large \rightarrow \: \:2x \: = \: 2$

$\bf \Large \rightarrow \: \:x \: = \: \cancel\frac{2}{2} \: \large \: ^{1} \: = \: 1$

$\bf \Large \rightarrow \: \:x \: = \: 1$

Option ( A ) is the correct answer.
