\fbox{\textsf{17}}

\mathbb{\bold{\underline{EXPLANATION:}}}

\star \to \textsf{11 added to twice a number gives 45}

\colon \to \textbf{To create an equation :}

\to \textsf{Let the number be \textbf{'n'}}

\star \textsf{ Twice a number \to$ 2 x n = \textbf{2n}}

\star \textsf{ 11 added to twice a number \to$ 11 + (2 x n) = \textbf{11 + 2n}}

\to \textsf{Since 11 added to twice a number gives 45, so, we have the equation :}

\star \star \textbf{ 11 + 2n = 45}

\colon \to \textbf{To solve the equation :}

\star \textsf{ 11 + 2n = 45}

\to \textsf{2n = 45 - 11}

\to \textsf{2n = 34}

\to \textsf{n = 34/2}

\to \textsf{n = 17}

\textbf{\therefore$ The number is 17}

Answer:

Let the required number be x.

Given : twice the number +11 = 45

 \: 2x + 11 = 45 \\ 2x  = 45 - 11 \\ 2x = 34 \\ x =  \frac{34}{2}  = 17

Hence,the required number is 17.
