Answer:
D
Step-by-step explanation:
Remember, |n|≥0 for all real numbers n
so
-|x|=0
times -1
|x|=0
true, x=0, has a solution
|x|=-15
false, can't have negative absolute value
-|x|=12
|x|=-12
false, no negative absolute value
-|-x|=9
|-x|=-9
false, no negative absolute value
-|-x|=-2
|-x|=2
x=2 or -2
true, has solutions
the ones that have no solutions are
|x|=-15
-|x|=12
-|-x|=9

I decided to do mental math and figured out it was -12. but you can cross multiply since both answers have to equal one another. you will still get the answer.
Bevin by multiplying both sides of the equation by 2, so you get x-6=3x+8. Next, move variable to the left side and change its sign, so you get x-3x-6=8. Then, collect the like terms, so you get -2x=14. Lastly, divide both sides by -2 to isolate the variable (x). The answer is x=-7
