2|x|-10=22

OpenStudy (anonymous):

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?

jimthompson5910 (jim_thompson5910):

no, 16 or -16

OpenStudy (anonymous):

33/2 is 16.5

myininaya (myininaya):

hero you can say it like that if you want it means the samething as what jim has

hero (hero):

Okay

OpenStudy (anonymous):

oh wait it is 32!!!!

jimthompson5910 (jim_thompson5910):

same thing, no big deal really

jimthompson5910 (jim_thompson5910):

yes it's 32 not 33

OpenStudy (anonymous):

its -16 and 16 correct?

jimthompson5910 (jim_thompson5910):

yes you got it

myininaya (myininaya):

or*? yes

jimthompson5910 (jim_thompson5910):

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):

but as long as you have the numbers, that should be fine imo

OpenStudy (anonymous):

OpenStudy (anonymous):

thats why i put a comma..

jimthompson5910 (jim_thompson5910):

lol yes, the comma will work perfectly

OpenStudy (anonymous):
