Third option, last one
Step-by-step explanation:
Let's solve for x first.
|2x| - 12 = -2
|2x| = 10
2x = 10 or -2x = 10
x = 5 or x = -5
The number line that represents this is the last one.
Every 10 you multipy by moves the decimla place to the right by 1 place
so it moves 1 place so therefor you need to multipy it by 10 ONE time
answer is 1 times
