Explanation:

The question is incomplete. However, you can make use of the following tips to answer your question.

We have that:

`x = 10.8`

`x + 29.2 = 40`

because

`10.8 + 29.2 = 40`

Another possible expression is:

`50.8 - x = 40`

This is so, because:

`50.8 - 10.8 = 40`

Another one is:

`2x + 18.4 = 40`

This is so because:

`2 * 10.8 + 18.4 = 40`

So, all you need to do is to substitute 10.8 for x in the given expression,

If the solution equates to 40, then that's your answer
