x= 16 1/2, -16 1/2?

jimthompson5910 (jim_thompson5910):
\[\large 2|x|-10=22\]
\[\large 2|x|=22+10\]
\[\large 2|x|=32\]
\[\large |x|=\frac{32}{2}\]
\[\large |x|=16\]
\[\large x=16 \textrm{ or } x=-16\]

OpenStudy (anonymous):
no, steps are
1) add 10 to both sides
2) divide both sides by 2
3) remove absolute value signs, write plus or minus

hero (hero):
What's wrong with saying \[x = \pm16\]

OpenStudy (anonymous):
so its 16.5 and -16.5?

yes if you want to be technical, but he's got the right idea

myininaya (myininaya):
lol

jimthompson5910 (jim_thompson5910):
its really "or" because x can't be two values at once

jimthompson5910 (jim_thompson5910):
