Question

1/2x+2/3(x-1)=1/3

Answer 1

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

`1/2 x + 2/3 x - 2/3 = 1/3`

`(1/2 + 2/3) .x = 1/3 + 2/3`

`7/6 x=1`

`x=1 : 7/6`

`x=6/7`

Answer 2

Ta có: \(\dfrac{1}{2}x+\dfrac{2}{3}\left(x-1\right)=\dfrac{1}{3}\)

\(\Leftrightarrow\dfrac{1}{2}x+\dfrac{2}{3}x=\dfrac{1}{3}+\dfrac{2}{3}=1\)

\(\Leftrightarrow\dfrac{7}{6}x=1\)

hay \(x=\dfrac{6}{7}\)
