Question

[Name guitar]

\(\dfrac{1}{3}\)x+\(\dfrac{2}{3}\)x=\(\dfrac{-7}{6}\)

Ai đó chỉ bài này với 

Answer 1

[2611]

`1/3x+2/3x=[-7]/6`

`(1/3+2/3)x=[-7]/6`

`3/3x=[-7]/6`

`x=[-7]/6`

Answer 2

[Chuu]

\(x.\left(\dfrac{1}{3}+\dfrac{2}{3}\right)=-\dfrac{7}{6}\)

\(x.1=-\dfrac{7}{6}\)

\(x=-\dfrac{7}{6}:1\)

\(x=-\dfrac{7}{6}\)
