For how many values of W, is |||W - 5| -10| -5| = 2?
(Those ls are mods)  Choose the correct choice from the following.
A) 0 B) 2 C) 4 D) 8 E) More than 8
I think its 8   |||W-5|-10|-5| =2   let |W-5| = a which makes above   ||a-10|-5| =2   let |a-10| = b which makes   |b-5| = 2   now for the above b can take 3, 7   for every b =3 a can have 13, 7   and for b = 7 a can have 17 and 3   so 'a' has four solutions 13, 7, 17 and 3   for a = 13; W has 18 or -8 thus has 2 for every combination hence 4x2 = 8   answer 8
