A) is the answer.

compassionate · Answer

I say this because, x, and, 7, are in parenthesis and should be treated as one. 

Do you understand?

compassionate · Answer

Anything in parenthesis can be considered a sum.

yes but i thought it would of been the 3rd one

anonymous · Answer

@Compassionate  thank you for clarity

anonymous · Answer

no, the answer is a, there no minus in the answer

compassionate · Answer

"Two times x minus seven plus ten." 

That is saying:

2x - 7 + 10 

You see, it is being subtracted from 7. It needs to be a sum.
