Answer:
No Solution
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle \large{|x|-5=-20}[/tex]
First, Add both sides by 5 which leaves us [tex]\displaystyle \large{|x|=-15}[/tex]
By definition, an absolute value cannot be negative. There are no x-values that can equal to -15 because no matter what real numbers you put in or substitute, it will never become negative.
Hence, no solution.
