Solve |x| = 5 would the answer be {5}?

OpenStudy (anonymous):

You're looking for numbers that are 5 units away from 0 on a number line. 5 does fit this description, but -5 also works if you go in the negative direction (because -5 is still five units away from 0) Your solution set is {-5, 5}

Yeah, x could also be -5 and still get 5 for the |x|.
