hi!!
OpenStudy (misty1212):
\[\frac{2}{3}(x-4)=2x?\] right?

Yes
OpenStudy (misty1212):
i hate fractions
OpenStudy (misty1212):
multiply both sides by 3 and get
\[2(x-4)=6x\] is a good start
OpenStudy (anonymous):
I get everything except the 2x part
OpenStudy (anonymous):
Multiply the 2/3 by x/1

What do you mean ?
OpenStudy (misty1212):
your fraction in front is \(\frac{2}{3}\) right?
OpenStudy (anonymous):
Yes
OpenStudy (anonymous):
Make the -4 12/3 and keep that 2/3x
OpenStudy (anonymous):
And make the 2x , 6/3x, it'll make it all Easter if it's all fractions

lets go slow
OpenStudy (jdoe0001):
\(\bf \cfrac{2}{3}(x-4)=2x\implies \cfrac{2(x-4)}{{\color{brown}{ 3}}}=2x
\\ \quad \\
2(x-4)={\color{brown}{ 3}}(2x)\implies 2x-8=6x\implies ?=x\)

want a picture of wavy I'd do ?
OpenStudy (anonymous):
I don't wanna push you guys but can you do the problem step-by-step because im not getting anything? It would be helpful.
OpenStudy (anonymous):
Sure retro

Thanks jdoe
OpenStudy (anonymous):
I wanna see everyone of your answer with your ways and see which one easiest so I can do them on my own later :D
OpenStudy (misty1212):
\[\frac{2}{3}(x-4)=2x\] the annoying part is the fraction \(\frac{2}{3}\) we can get rid of the denominator by multiplying both sides by 3
OpenStudy (anonymous):
Okay so 2x would be 6x....
OpenStudy (misty1212):
that will get rid of the fraction
\[3\times \frac{2}{3}(x-4)=3\times 2x\\
2(x-4)=6x\]

Won't let me post picture
OpenStudy (misty1212):
then it should be more or less routine
distribute first get
\[2x-8=6x\]
OpenStudy (misty1212):
subtract \(2x\) from both sides to get
\[-8=4x\]
OpenStudy (anonymous):
I got the answer
OpenStudy (misty1212):
then divide both sides by \(4\)
