whats the question?
OpenStudy (anonymous):
divide both sides by 2 and start with
\[6(x-6)=x-9\] then distribute to get
\[6x-36=x-9\]

That doesn't work tho. it's wrong
OpenStudy (anonymous):
\[x=\frac{ 27 }{ 5 }\]
OpenStudy (anonymous):
doesn't work its a number and then a fraction \[ \frac{ }{ }\]
OpenStudy (anonymous):
there is no number its just x which is the variable
OpenStudy (anonymous):
It needs to be written as a reduced, mixed number.

if you plug in 27/5 for the variable each side comes out to -7.2
OpenStudy (anonymous):
im positive that's the answer
OpenStudy (anonymous):
so we have 12(x -6) = 2(x - 9)
OpenStudy (anonymous):
you plug in 27/5
OpenStudy (anonymous):
for x

so then we have 12(27/5 -6) = 2(27/5 - 9)
OpenStudy (anonymous):
and each side come out to this -7.5=-7.5
OpenStudy (anonymous):
understand?
OpenStudy (anonymous):
I understand what you are saying, but I think it's looking for something else. It's not accepting either of those as an answer.
OpenStudy (anonymous):
then im not sure haha

haha okay, thanks for trying.
OpenStudy (anonymous):
x = 5 2/5. Apparently that's the answer. hmm.
OpenStudy (anonymous):

OpenStudy (anonymous):
yeah...
OpenStudy (anonymous):
but I was technically right :)
