$\huge \mid{ \underline{ \overline{ \underline{\overline \pink{\bold{ \: \: Aɴsᴡᴇʀ \: \: } }}} }}\mid$

let the number be x

then according to the question

$2x - 3 = 13 \: \: \: \: \\ \\ \implies 2x = 13 + 3 \\ \\ \implies x = \cancel \frac{16}{2} \: \: \: \: \: \: \: \: \: \\ \\ \implies \boxed{x = 8} \: \: \: \: \: \: \: \:$

so, your number is 8
