Absolute value just makes any number positive no matter what

Isolate the x before....

Answer 10

Haha, you're making this more complicated than you need to :)

Answer 11

Just isolate your x like in a normal equation and you get l x l = 3

Answer 12

Your equation is
lxl - 8 = -5

You don't change any number except for the number you are taking the absolute value of. So plugging 13 in for x will just equal out to be 5.
You can't change the signs of any other number outside of the absolute values parenthesis.
