I would say B because instead of distributing the 2 you could easily divide both sides by 2 and save the hassle of dividing by 2 later. Also A C and D seem to all be saying relatively the same thing. edit: But then again it seems like a tricky question

1.)18 = 2(4 + x) ||
2.) 18 = 8 + 2x --- Distribute. ||
3.) 10 = 2x --- Isolate the variable by collecting like terms ||
4.) 5 = x

I'd say A. is a good choice.
