Question

-4/7 - x = 3/5 -2x

Answer 1

\(-\dfrac{4}{7}-x=\dfrac{3}{5}-2x\)

\(\Rightarrow x=\dfrac{3}{5}+\dfrac{4}{7}=\dfrac{41}{35}\)

Answer 2

`-4/7-x=3/5-2x`

`<=>-x+2x=3/5+4/7`

`<=>x=7/5`

Vậy `x=7/5`

Answer 3

\(-\dfrac{4}{7}-x=\dfrac{3}{5}-2x\)

\(\Leftrightarrow x=\dfrac{3}{5}+\dfrac{4}{7}=\dfrac{41}{35}\)
