x=???
`(x + 5)` x `\frac{3}{13}` `=` `\frac{2}{3}`
`(x + 5)` `=` `\frac{2}{3}` `:` `\frac{3}{13}`
`(x + 5) =` `\frac{26}{9}`
`x` `=` `\frac{26}{9}` `-` `5`
`x` `=` `\frac{-19}{9}`
Vậy, `x` `=` `\frac{-19}{9}`

Đáp án:
(`x`+$\dfrac{5}{3}$)x$\dfrac{3}{13}$=$\dfrac{2}{3}$
`=>` `x`+$\dfrac{5}{3}$=$\dfrac{2}{3}$:$\dfrac{3}{13}$
`=>` `x`+$\dfrac{5}{3}$=$\dfrac{2}{3}$x$\dfrac{13}{3}$
`=>` `x`+$\dfrac{5}{3}$=$\dfrac{2×13}{3×3}$
`=>` `x`+$\dfrac{5}{3}$=`26`
`=>` `x`=`26`-$\dfrac{5}{3}$
`=>` `x`=$\dfrac{78}{3}$-$\dfrac{5}{3}$
`=>` `x`=$\dfrac{73}{3}$
`\text{Vậy x}` =$\dfrac{73}{3}$
