Question

Tìm x biết: 
3/4-1/4.x=5/6

Answer 1

1/4 .x = 3/4 - 5/6

1/4  .x = -1/12

x = -1/12 : 1/4

x = -1/3

Answer 2

\(\dfrac{3}{4} - \dfrac{1}{4}x=\dfrac{5}{6}\)

\( \dfrac{1}{4}x=\dfrac{3}{4} -\dfrac{5}{6}\)

\( \dfrac{1}{4}x=\dfrac{-1}{12} \)

\(x=\dfrac{-1}{12} : \dfrac{1}{4}\)

\(x = \dfrac{-1}{3}\)

Vậy \(x = \dfrac{-1}{3}\)

 

Answer 3

\(\dfrac{3}{4}-\dfrac{1}{4}.x=\dfrac{5}{6}\)

\(\dfrac{1}{4}.x=\dfrac{3}{4}-\dfrac{5}{6}\)

\(\dfrac{1}{4}.x=\dfrac{-1}{12}\)

\(x=\dfrac{-1}{12}:\dfrac{3}{4}\)

\(x=\dfrac{-1}{3}\)
