`4/3-13/15x=2/5`
`13/15x=4/3-2/5`
`13/15x=14/15`
`x=14/15:13/15`
`x=14/13`
Vậy `x=14/13`
\(\dfrac{4}{3}-\dfrac{13}{15}.x=\dfrac{2}{5}\)
\(x=\left(\dfrac{4}{3}-\dfrac{2}{5}\right):\dfrac{13}{15}\)
\(x=\dfrac{14}{13}\)
Chúc bạn học tốt!! ^^
\(\dfrac{4}{3}-\dfrac{13}{15}.x=\dfrac{2}{5}\)
\(\rightarrow x=\dfrac{\left(\dfrac{4}{3}-\dfrac{2}{5}\right)}{\dfrac{13}{15}}\)
\(\rightarrow x=\dfrac{14}{13}\)
Vậy \(:x=\dfrac{14}{13}\)
\(\dfrac{4}{3}-\dfrac{13}{15}.x=\dfrac{2}{5}\)
\(\dfrac{13}{15}.x=\dfrac{4}{3}-\dfrac{2}{5}\)
\(\dfrac{13}{15}.x=\dfrac{14}{15}\)
\(x=\dfrac{14}{15}:\dfrac{13}{15}\)
\(x=\dfrac{14}{13}\)
Chúc bạn học tốt!
\(\dfrac{4}{3}-\dfrac{13}{15}.x=\dfrac{2}{5}\)
\(\dfrac{13}{15}.x=\dfrac{4}{3}-\dfrac{2}{5}\)
\(\dfrac{13}{15}.x=\dfrac{20}{15}-\dfrac{6}{15}\)
\(\dfrac{13}{15}.x=\dfrac{14}{15}\)
\(x=\dfrac{14}{15}:\dfrac{13}{15}\)
\(x=\dfrac{14}{15}.\dfrac{15}{13}\)
\(x=\dfrac{14}{13}\)
Vậy \(x=\dfrac{14}{13}\)
