Consider the following word problem:

"The sum of a number and 5 is 7 less than its double".

To solve the word problem, let n be the number.


\begin{gathered} \text{Therefore, the sum of the number and 5 is given by:} \\ n+5 \end{gathered}
\begin{gathered} \text{ double the number is given by:} \\ 2n \end{gathered}


\begin{gathered} \text{Therefore, the sum of the number and 5 is given by:} \\ n+5=2n-7 \end{gathered}

Hence, the solution is given by:


\begin{gathered} 5+7=2n-n \\ n=12 \end{gathered}

Therefore, the required word problem is: "The sum of a number and 5 is 7 less than its double" ; the acceptable answer to the word problem is 12 and any number that is not 12 will not be acceptable.
