Question

1/2.x-1/4=-1/2

 

Answer 1

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

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

\(=>2x-1=-2\)

\(=>2x=-1\)

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

Answer 2

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

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

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

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

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

\(x=-\dfrac{1}{2}\)

Answer 3

1/2x- 1/4= -1/2
1/2x= -1/2+ 1/4
1/2x= -1/4
x= -1/4 : 1/2
x=-1/2(hết)

Answer 4

`1/2 . x -1/4 =-1/2`

`=> 1/2 . x= -1/2 +1/4`

`=> 1/2 . x=-2/4 +1/4`

`=> 1/2 . x= -1/4`

`=> x=-1/4 :1/2`

`=> x= -1/4 xx 2`

`=>x=-2/4`

`=>x=-1/2`
