Answer 1

\(x\times2+x\times\frac{1}{5}=1\frac{3}{5}\)

\(x\times\left(2+\frac{1}{5}\right)=\frac{8}{5}\)

\(x\times\frac{11}{5}=\frac{8}{5}\)

\(x=\frac{8}{5}\div\frac{11}{5}\)

\(x=\frac{8}{11}\)

Answer 2

\(\Rightarrow x.\left(2+\frac{1}{5}\right)=\frac{8}{5}\)

\(\Rightarrow\frac{11}{5}x=\frac{8}{5}\)

\(\Rightarrow x=\frac{8}{11}\)

Answer 3

       Bài làm :

Ta có :

\(x\times2+x\times\frac{1}{5}=1\frac{3}{5}\)

\(\Leftrightarrow x\times\left(2+\frac{1}{5}\right)=\frac{8}{5}\)

\(\Leftrightarrow x\times\frac{11}{5}=\frac{8}{5}\)

\(\Leftrightarrow x=\frac{8}{5}\div\frac{11}{5}\)

\(\Leftrightarrow x=\frac{8}{11}\)

Vậy x=8/11

Answer 4

\(x×2+x×\frac{1}{5}=1\frac{3}{5}\)

\(x×2+x×\frac{1}{5}=\frac{8}{5} \)

\(x×\left(2+\frac{1}{5}\right)=\frac{8}{5}\)

\(x×\frac{11}{5}=\frac{8}{5}\)

\(x=\frac{8}{5}:\frac{11}{5}\)

\(x=\frac{8}{11}\)

vậy \(x=\frac{8}{11}\)
