ok so I have it this far and I'm stuck... see below...

OpenStudy (anonymous):

You didn't get very far :/

myininaya (myininaya):

lol

OpenStudy (anonymous):

\[\left(\begin{matrix}5 \\ 2x\end{matrix}\right)+\left(\begin{matrix}8 \\ x\end{matrix}\right)\]=1 \[2x \left(\begin{matrix}5 \\ 2x\end{matrix}\right)+\left(\begin{matrix}8 \\ x\end{matrix}\right)=2x \times1\] \[2x \times \left(\begin{matrix}5 \\ 2x\end{matrix}\right)+2x\left(\begin{matrix}8 \\ x\end{matrix}\right)=2x \times1\]

OpenStudy (anonymous):

I was typing it

myininaya (myininaya):

?

OpenStudy (anonymous):

Um.. hmm well I came up with 21/2x

OpenStudy (anonymous):

oh yeah sorry I need to solve for x

myininaya (myininaya):

are those suppose to be fractions?

OpenStudy (anonymous):

how so?

OpenStudy (anonymous):

yeah, I don't know how to do them on here

OpenStudy (anonymous):

OHHHH I'm sorry! I didn't see the =1

myininaya (myininaya):

frac{}{}

OpenStudy (anonymous):

ok thanks I'll remember that

OpenStudy (anonymous):

2x=21 or x=21/2 then

OpenStudy (anonymous):

ok that's actually what I got just making sure, I thought I was missing something

myininaya (myininaya):

\[\frac{5}{2x}+\frac{8}{x}=1\] \[2x*(\frac{5}{2x}+\frac{8}{x}=1)\] \[5+16=2x\] right shark

OpenStudy (anonymous):

Yes sir myininaya.. multiply it by 2x because it's the LCD

OpenStudy (anonymous):

these binomials??

myininaya (myininaya):

i guess i will let you get a away with calling me sir

OpenStudy (anonymous):

hello sir

OpenStudy (anonymous):

Thank you, maybe I just need to stop second guessing myself with this stuff

myininaya (myininaya):

fractions i already asked

OpenStudy (anonymous):

Erm.. Sorry >.< Yes ma'am! haha

OpenStudy (anonymous):

what i am supposed to read? thought this was a math site!

OpenStudy (anonymous):

Can you guys help me with one more?

OpenStudy (anonymous):

ok which one makes fractions?

OpenStudy (anonymous):

\[\frac{x+5}{x-2}=\frac{x-2}{x+4}\]

OpenStudy (anonymous):

cross multiply
