Question

tìm X

2/3 : x +2/3 = 1/6

Answer 1

\(\dfrac{2}{3}\div x+\dfrac{2}{3}=\dfrac{1}{6}\)

\(\dfrac{2}{3}\div x=\dfrac{1}{6}-\dfrac{2}{3}\)

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

       \(x=\dfrac{2}{3}\div\left(-\dfrac{1}{2}\right)\)

       \(x=-\dfrac{4}{3}\)

Answer 2

\(\dfrac{2}{3}:x+\dfrac{2}{3}=\dfrac{1}{6}\)

\(\Leftrightarrow\dfrac{2}{3}:x=\dfrac{1}{6}-\dfrac{2}{3}\)

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

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

\(\Leftrightarrow x=-\dfrac{4}{3}\)

Answer 3

2/3 : x + 2/3 = 1/6

2/3 : x          = 1/6 - 2/3

2/3 : x          = -1/2

        x          = 2/3 : (-1)/2

        x          = -4/3

vậy x =....
