Answer: 2 and -4
Explanation:
tiffanyrenaew21 is not completely right. The correct answer would be 2 and -4. This is how you find your answer:
First you form an equation: |x-(-1)|=3
|x+1|=3 - - - - - - - - |x+1|=-3
Subtract 1 from both sides
x=2 - - - - - - - - - - x=-4
You will always have 2 answers as absolute value equations and inequalities can always be positive or negative. |positive or negative| = positive.
If |x|=-n, then there are no solutions, becuase absolute value can't be negative.
