Question

Tìm x

Biết: 14:(x - 1/4) = 7

Answer 1

14:(x-\(\dfrac{1}{4}\))=7

<=>x-\(\dfrac{1}{4}\)=\(\dfrac{1}{2}\)

<=>x=\(\dfrac{1}{2}+\dfrac{1}{4}\)

<=>x=\(\dfrac{3}{4}\)

Vậy x=\(\dfrac{3}{4}\)

Answer 2

\(14:\left(x-\dfrac{1}{4}\right)=7\)

<=> 14 : x - \(14:\dfrac{1}{4}=7\)

<=> \(\dfrac{14}{x}-56=7\)

<=> \(\dfrac{14}{x}=63\)

<=> x = \(\dfrac{14}{63}=\dfrac{2}{9}\)
