Question

Half of the difference of nine and e is the same as four less than e

Answer 1

"half of the difference of nine and e" can be written as

`(1)/(2)(9-e)`

and "four less than e" is

`4-e`

If they are the same, we can write:

`\begin{gathered} (1)/(2)(9-e)=4-e \\ 9-e=2(4-e) \\ 9-e=8-2e \\ -e+2e=8-9 \\ e=-1 \end{gathered}`

The value of e is e=-1.
