3+ means 3 and up hope i could help.
The 3rd one because when you find the absolute value of a number, it will always be positive. So the list would be 3.5, 4.2, 9
you pick one candy at random.
You need to distribute the 4, so you'll end up with:
4n-16=-12
Then, add 16 to both sides.
4n-16+16=-12+16
4n=4
Divide by 4 on both sides.
4/4n=4/4
n=1
