`23/x + 3/4 = -1/2 : 5`
`=>23/x + 3/4 = -1/2 . 1/ 5`
`=>23/x+3/4=-1/10`
`=>23/x=-1/10-3/4`
`=>23/x=-17/10`
`=>x=-(23.10)/17`
`=>x=-460/17`
Vậy `x=-460/17`
$\dfrac{23}{x}$+$\dfrac{3}{4}$ =$\dfrac{-1}{2}$ :${5}$
$\dfrac{23}{x}$ +$\dfrac{3}{4}$ =$\dfrac{-1}{10}$
$\dfrac{23}{x}$=$\dfrac{-1}{10}$ -$\dfrac{3}{4}$
$\dfrac{23}{x}$=$\dfrac{-17}{20}$
Vậy ${x}$=${23×20:-17}$= $\dfrac{-460}{17}$
