Answer:
27
Step-by-step explanation:
Hello,
do you agree that
[tex]\dfrac{1}{3}-\dfrac{1}{9}=\dfrac{3-1}{9}=\dfrac{2}{9}[/tex] ?
Then,
we can simplify as below and multiply by 9 both sides and divide by 2
[tex]\dfrac{x}{3}-\dfrac{x}{9}=\dfrac{2x}{9}=6\\\\<=> 2x = 54\\\\<=> x = 54/2= 27[/tex]
Thanks
