Question

Answer 1

`1/3x -2/3  = 1/2(1/4-4)`

`1/3x -2/3 =1/8 - 4/2 = 1/8 - 16/8`

`1/3x -2/3 = -15/8`

`=> 1/3x = -15/8 + 2/3 = -29/24`

`=> x = -29/24 : 1/3 = -29/24 * 3`

`x = -29/8`

Vậy `x=-29/8`

Answer 2

\(\dfrac{1}{3}x-\dfrac{2}{3}=\dfrac{1}{8}-2\Leftrightarrow\dfrac{1}{3}x=-\dfrac{29}{24}\Leftrightarrow x=-\dfrac{29}{8}\)

Answer 3

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

`=>1/3 x -2/3 =1/2. (-15)/4`

`=>1/3 x -2/3 =-15/8`

`=> 1/3 x =-15/8+2/3`

`=> 1/3 x =-29/24`

`=>x=-29/24 : 1/3`

`=>x=-29/24 xx 3`

`=>x= -29/8`
