\(\left|x-23.4\right|=23.4\\ \\ \\\Rightarrow\left|x-92\right|=92\\ \\ \\ \Rightarrow\left[{}\begin{matrix}x-92=92\\-x+92=92\end{matrix}\right. \Rightarrow\left[{}\begin{matrix}x=92+92=19=184\\-x=92-92=0\Rightarrow x=0\end{matrix}\right.\)

Vậy x=184; x=0

\(\dfrac{16}{15}=1,0\left(6\right)\approx1,1\)
