`4/7+5x=3/2`
`5x=3/2-4/7`
`5x=21/14-8/14`
`5x=13/14`
`x=13/14:5`
`x=13/70`
Vậy `x=13/70`
\(\dfrac{4}{7}+5x=\dfrac{3}{2}\\ 5x=\dfrac{3}{2}-\dfrac{4}{7}\\ 5x=\dfrac{13}{14}\\ x=\dfrac{13}{14}:5=\dfrac{13}{70}\)
\(\dfrac{4}{7}+5x=\dfrac{3}{2}\)
\(5x=\dfrac{3}{2}-\dfrac{4}{7}\)
\(5x=\dfrac{13}{14}\)
=>x= \(\dfrac{13}{70}\)
\(\dfrac{4}{7}+5x=\dfrac{3}{2}\)
\(5x=\dfrac{3}{2}-\dfrac{4}{7}\)
\(5x=\dfrac{13}{14}\)
\(x=\dfrac{13}{14}:5\)
\(x=\dfrac{13}{70}\)
Ta có: \(5x+\dfrac{4}{7}=\dfrac{3}{2}\)
\(\Leftrightarrow5x=\dfrac{3}{2}-\dfrac{4}{7}=\dfrac{21}{14}-\dfrac{8}{14}=\dfrac{13}{14}\)
hay \(x=\dfrac{13}{70}\)
Vậy: \(x=\dfrac{13}{70}\)
\(\dfrac{4}{7}+5x=\dfrac{3}{2}\)
\(5x=\dfrac{3}{2}-\dfrac{4}{7}\)
\(5x=\dfrac{21}{14}-\dfrac{8}{14}\)
\(5x=\dfrac{13}{14}\)
\(x=\dfrac{13}{14}:5\)
\(x=\dfrac{13}{14}.\dfrac{1}{5}\)
\(x=\dfrac{13}{70}\)
Vậy x = \(\dfrac{13}{70}\)
