@dude I MESSED UP
dude:
What happened?
EndersWorld:
\[\frac{ 4x }{ 3 } = 2(x+9)\]
-54
-27
-6.75
-4.5
27
EndersWorld:
Not a single one fit in... they were all wrong when I worked them out.
EndersWorld:
Want me to post all my work?

Hmm well lets solve this algebraically
\(\large {\frac{4x}{3}}=2(x+9)\)
Lets distribute the 2
EndersWorld:
|dw:1524090080393:dw|
dude:
Right
\(\large {\frac{4x}{3}}=2(x+9)\)
\(\large \frac{4x}{3}=2x+18\)
To get rid of the fraction, we can multiply both sides of the equation by 3
EndersWorld:
|dw:1524090229016:dw|
dude:
Right
\(4x=6x+54\)
Now we want to get x on one side of the equation

I’m dumb...
dude:
To check
\(\large \frac{ 4x }{ 3 } = 2(x+9)\\
\large \frac{ 4\cdot-27 }{ 3 } = 2(-27+9)\\
\large \frac{-108}{3}=2(-18)\\
\large\frac{-108}{3}=-36\\
-36=-36\)
EndersWorld:
Thank you!

dude:
