|3x+7|≥2x+12 which of the following is x value:

x≤−195 or
x≥5 (E)
−195<x<5After solving the inequality I got the two answers X >=5 and X <= -19/5. but since this is an absolute question I checked each answer by plug in the two possible answers in the original equation and I found that x <= -19/5 is an erroneous value, so I chose answer choice (C) as the correct answer, but the book gives (D) as the correct answer. what I'm missing here

|3x+7|≥2x+12 is true when
x≥5 or
x≤195. Which is option D.
P.S. Does the question is worded
exactly as you written? Does it say "which of the following is x value"?
