Question

Tìm X

1/3 + 3/X x 5 = 11/6

Answer 1

\(\dfrac{1}{3}+\dfrac{3}{x}\times5=\dfrac{11}{6}\)

\(\Rightarrow\dfrac{3}{x}\times5=\dfrac{11}{6}-\dfrac{1}{3}\)

\(\Rightarrow\dfrac{3}{x}\times5=\dfrac{3}{2}\)

\(\Rightarrow\dfrac{3}{x}=\dfrac{3}{2}:5\)

\(\Rightarrow\dfrac{3}{x}=\dfrac{3}{10}\)

\(\Rightarrow x=10\)

Answer 2

`1/3 + 3/x xx 5 = 11/6`

`= >     15/x         = 11/6 - 1/3`

`=>        15/x       =3/2`

`=> 15/x             = 15/10`

`=> x = 10`

Vậy `x = 10`
