`|3x-4,5|-|2x-5|=0`
`=>|3x-4,5|=|2x-5|`
`=>`\(\left[ \begin{array}{l}3x-4,5=2x-5\\3x-4,5=5-2x\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}3x-2x=-5+4,5\\3x+2x=5+4\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}x=-\dfrac{1}{2}=-0,5\\5x=9\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}x=-0,5\\x=\dfrac{9}{5}=1,8\end{array} \right.\)
Vậy `x \in {-0,5 ; 1,8}`
