9|9 - 8x| = 2x + 3

OpenStudy (anonymous):

do you distribute the 9?

OpenStudy (anonymous):

\[9|9 - 8x| = 2x + 3\] \[|9 - 8x| = \frac{2x + 3}{9} \] \[9 - 8x = \pm (\frac{2x}{9} + \frac{3}{9} )\] \[9 - 8x = \pm (\frac{2x}{9} + \frac{1}{3} )\]

hartnn (hartnn):

if you want to avoid fractions initially, you can also solve these separately, \(-9(9-8x)=2x+3\) and \(9(9-8x)=2x+3\)

hartnn (hartnn):

and now yes, you distribute the 9

OpenStudy (anonymous):

78 - 10x ?

hartnn (hartnn):

you forgot to distribute 9 to 8x ??

OpenStudy (anonymous):

......ohhh hahahaha

OpenStudy (anonymous):

now i have 78 = 78 x ....

hartnn (hartnn):

for this : 9(9−8x)=2x+3 81-72x=2x+3 78=74x isn't it ?

OpenStudy (anonymous):

I added it wrong haha you're right you're right. So now we divide yes?

hartnn (hartnn):

yes

OpenStudy (anonymous):

Alright got it thanks :)

hartnn (hartnn):

but we need to solve this too,similarly : −9(9−8x)=2x+3 and get other value of x

OpenStudy (anonymous):

:| lol dang it

hartnn (hartnn):

its easy :)

OpenStudy (anonymous):

will it just be the same thing but in negative ? haha

hartnn (hartnn):

no, solve it from first step, to see the difference..... :P

OpenStudy (anonymous):

84 = -70x lol yeah its a tad different haha

hartnn (hartnn):

wouldn't that be -84 ??

OpenStudy (anonymous):

Probably.... I'm the worst at negatives

hartnn (hartnn):

it'll be -84 so, x= -84/-70 = ... ?

OpenStudy (anonymous):

6 ovaaaa 5

OpenStudy (anonymous):

woo woo

OpenStudy (anonymous):

no wait

OpenStudy (anonymous):

3/5 ???? im confusing myself

hartnn (hartnn):

waiting

OpenStudy (anonymous):

3/5 final answer

hartnn (hartnn):

6/5 was correct :P

OpenStudy (anonymous):

dang flabbit

hartnn (hartnn):

any doubts ?

OpenStudy (anonymous):
