Question 777496: Excuse me, I need help figuring out what this question is asking for. Could you explain it to me?
31. Write and solve an absolute-value equation that represents two numbers x that are 2 units from 7 on a number line.

You can put this solution on YOUR website!
If x is 2 units from 7 on a number line, the distance between x and 7 is 2.
number_line%28800%2C-5%2C10%2C5%2C7%2C9%29
The difference between x and 7 is 2 in absolute value
highlight%28abs%28x-7%29=2%29
Either x-7=2 <--> x=7%2B2 <--> highlight%28x=9%29,
or 7-x=2 <--> x-7=-2 <--> x=7-2 <--> highlight%28x=5%29
