`#Sad`
`1/4+1/3 : |2x-1| = (11)/(12)`
`⇔ 1/3 : |2x-1| = 2/3`
`⇔ |2x-1| = 1/2`
`⇔` \(\left[ \begin{array}{l}2x-1=\dfrac{1}{2}\\2x-1=-\dfrac{1}{2}\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}2x=\dfrac{3}{2}\\2x=\dfrac{1}{2}\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}x=\dfrac{3}{4}\\x=\dfrac{1}{4}\end{array} \right.\)
`\text{Vậy}` `x=3/4` `\text{hoặc}` `x=1/4`
