Question

  giúp mik làm bài này với ạ . Toán lớp 6

Answer 1

`x-2/3=3/4`

`=>x=3/4 + 2/3`

`=> x= 9/12 + 8/12`

`=>x= 17/12`

Answer 2

\(x-\dfrac{2}{3}=\dfrac{3}{4}\)

\(x=\dfrac{3}{4}+\dfrac{2}{3}=\dfrac{9}{12}+\dfrac{8}{12}\)

\(x=\dfrac{17}{12}\)

Answer 3

\(x-\dfrac{2}{3}=\dfrac{3}{4}\)
\(x=\dfrac{2}{3}+\dfrac{3}{4}\)
\(x=\dfrac{8}{12}+\dfrac{9}{12}\)
\(x=\dfrac{17}{12}\)
