Answer:
Step-by-step explanation:
When a number is taken by the square root, it will always come out positive. Looking at |x| = 5, there are two solutions for this that being 5 and -5.
|5| = 5
|-5| = 5
So if we plug those solutions into the expression x + 7, we get two different answers.
5 + 7 = 12
-5 + 7 = 2
