Answer:
12 = x
Step-by-step explanation:
The | | mean absolute value. Pretty much making every number within the sign a positive.
|-7| + 5 = x
7 + 5 = x
12 = x
Hope this helps.
Whenever you see this " | | " character, it means that whatever negative number in between those characters are always positive.
It converts -7 to just 7. This makes the question 7+5.
Giving you the answer 12.
