`5/4|2x-1/2|=7/8`
`⇔ |2x-1/2|=7/8÷5/4`
`⇔ |2x-1/2|=7/10`
`⇔` \(\left[ \begin{array}{l}2x-\dfrac{1}2=\dfrac{7}{10}\\2x-\dfrac{1}2=-\dfrac{7}{10}\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}2x=\dfrac{6}{5}\\2x=-\dfrac{1}{5}\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}x=\dfrac{3}{5}\\x=-\dfrac{1}{10}\end{array} \right.\)
Vậy `x=3/5` hoặc `x=-1/10`
Xin hay nhất !
