It depends on why do you write that way. If you did it on purpose, then I would accept it the same as writing x. But If you thought (by some reasons) that is should be 1x )but not x) then I would think that you didn't understand the difference between x and 1x.
But anyway, it should not change the overall evaluation significantly. At least I think so.
