23/x + 3/4 = -1/2 : 5

2 câu trả lời

`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 ${x}$=${23×20:-17}$= $\dfrac{-460}{17}$
