Question

Tìm x, biết: 1/3 : (2x - 1) = -4/24

Answer 1

`1/3 : (2x - 1) = (-4/24)`

`2x - 1 = 1/3 : (-4/24)`

`2x - 1 = -2`

`2x = (-2) + 1`

`2x = (-1)`

`x = 2 : (-1)`

`x = -2`

Answer 2

\(\dfrac{1}{3}:\left(2x-1\right)=\dfrac{-4}{24}\)

        \(2x-1=\dfrac{1}{3}:\left(\dfrac{-4}{24}\right)\)

        \(2x-1=-2\)

        \(2x=\left(-2\right)+1\)

         \(2x=-1\)

           \(x=2:\left(-1\right)\)

           \(x=-2\)

vậy x =...
