`a,`
`1/2 x -3/4 = 1 1/3`
`-> 1/2x - 3/4 = 4/3`
`-> 1/2x = 4/3 + 3/4`
`-> 1/2 x=25/12`
`->x=25/12 : 1/2`
`->x=25/6`
Vậy `x=25/6`
$\\$
`e,`
`|x-1/2| - 2 = 1/3`
`-> |x-1/2| = 1/3 + 2`
`-> |x-1/2|=7/3`
`->` \(\left[ \begin{array}{l}x-\dfrac{1}{2}=\dfrac{7}{3}\\x-\dfrac{1}{2}=\dfrac{-7}{3}\end{array} \right.\) $\\$ `->` \(\left[ \begin{array}{l}x=\dfrac{7}{3}+\dfrac{1}{2}\\x=\dfrac{-7}{3}+\dfrac{1}{2}\end{array} \right.\) $\\$ `->` \(\left[ \begin{array}{l}x=\dfrac{17}{6}\\x=\dfrac{-11}{6}\end{array} \right.\)
Vậy `x=17/6` hoặc `x=(-11)/6`
