Answer:
8 & 16
Step-by-step explanation:
Ix-12I = 4
This question is asking for the value(s) that when substituted in for x gives you the positive value of 4.
16 - 12 gives us 4 but because of the 2 lines around x-12, we can also use 8. Now normally, 8-12 gives us -4 but those line cause that -4 to become positive because its absolute value is 4. (absolute value basically means how far is the number from zero) (it helps to think about this on a number line and count the lines from zero, since you wouldn't count in negative, you'd count in positive ones.
So in the end our two options are 8 and 16.
(hope this helps and that I'm not completely wrong :))
