`2x-3/7=6 2/7`
`2x=6+2/7+3/7`
`2x=6+5/7`
`x=3+5/14=3 5/14`
Vậy `x=3 5/14`
Ta có: \(2x-\dfrac{3}{7}=6\dfrac{2}{7}\)
\(\Leftrightarrow2x=\dfrac{44}{7}+\dfrac{3}{7}=\dfrac{47}{7}\)
hay \(x=\dfrac{47}{14}\)
Vậy: \(x=\dfrac{47}{14}\)
\(2x-\dfrac{3}{7}=6\dfrac{2}{7}\)
\(2x-\dfrac{3}{7}=\dfrac{44}{7}\)
\(2x=\dfrac{44}{7}+\dfrac{3}{7}\)
\(2x=\dfrac{47}{7}\)
\(x=\dfrac{47}{7}:2\)
\(x=\dfrac{47}{7}.\dfrac{1}{2}\)
\(x=\dfrac{47}{14}\)
Vậy \(x-\dfrac{47}{14}\)
\(2x-\dfrac{3}{7}=6\dfrac{2}{7}\)
\(2x=\dfrac{44}{7}+\dfrac{3}{7}\)
\(2x=\dfrac{47}{7}\)
\(x=\dfrac{47}{7}:2\)
\(x=\dfrac{47}{14}\)
