`4/5|56/25x-14/15|=273/894`
`⇔ |56/25x-14/15|=273/894÷4/5`
`⇔ |56/25x-14/15|=455/1192`
`⇔` \(\left[ \begin{array}{l}\dfrac{56}{25}x-\dfrac{14}{15}=\dfrac{445}{1192}\\\dfrac{56}{25}x-\dfrac{14}{15}=-\dfrac{445}{1192}\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}\dfrac{56x}{25}≈1,3\\\dfrac{56x}{25}≈0,6\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}56x≈32,5\\56x≈15\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}x≈0,6\\x≈0,3\end{array} \right.\)
Vậy `x≈0,6;x≈0,3`
