The solution to the equation is?

EndersWorld:

@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?

dude:

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

EndersWorld:

|dw:1524090363363:dw|

EndersWorld:

|dw:1524090388092:dw|

dude:

Yes amd now lets divide by -2 on both sides =P

dude:

There is your answer

EndersWorld:

:0

EndersWorld:

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!

EndersWorld:

14 more :/

dude:

Lets get to them :P and no prob!
