Question

Tìm x:

2 : x - \(\dfrac{1}{3}=\dfrac{2}{5}\) 

Answer 1

`2:x-1/3=2/5`

`2:x=2/5+1/3`

`2:x=11/15`

`x=2:11/15`

`x=30/11`

Answer 2

\(2:x-\dfrac{1}{3}=\dfrac{2}{5}\)

\(2:x=\dfrac{2}{5}+\dfrac{1}{3}\)

\(2:x=\dfrac{6}{15}+\dfrac{5}{15}\)

\(2:x=\dfrac{11}{15}\)

\(x=2:\dfrac{11}{15}\)

\(x=2\times\dfrac{15}{11}\)

\(x=\dfrac{30}{11}\)
