12(x -6) = 2(x - 9)

OpenStudy (anonymous):

whats the question?

OpenStudy (anonymous):

divide both sides by 2 and start with \[6(x-6)=x-9\] then distribute to get \[6x-36=x-9\]

OpenStudy (anonymous):

Solve the following question. Answer as a reduced, mixed, number.

OpenStudy (anonymous):

pretty sure its x=27/5 right sat?

OpenStudy (anonymous):

aand to find answer you do what sat is saying

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

haha okay, thanks for trying.

OpenStudy (anonymous):

x = 5 2/5. Apparently that's the answer. hmm.

OpenStudy (anonymous):

oh lol all you had to do is convert it to a mixed number xD

OpenStudy (anonymous):

yeah...

OpenStudy (anonymous):

but I was technically right :)

OpenStudy (anonymous):

yuppers :) tankss
