\(\dfrac{2}{3}x+\dfrac{4}{5}=\dfrac{1}{2}\)

\(\Leftrightarrow\dfrac{2}{3}x=\dfrac{1}{2}-\dfrac{4}{5}\)

\(\Leftrightarrow\dfrac{2}{3}x=\dfrac{5}{10}-\dfrac{8}{10}\)

\(\Leftrightarrow\dfrac{2}{3}x=-\dfrac{3}{10}\)

\(\Leftrightarrow x=-\dfrac{3}{10}:\dfrac{2}{3}\)

\(\Leftrightarrow x=-\dfrac{3}{10}.\dfrac{3}{2}\)

\(\Leftrightarrow x=-\dfrac{9}{20}\)

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

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

`2x=7/6`

`x=7/6:2=7/12`

\(2x-\dfrac{2}{3}=\dfrac{1}{2}\Leftrightarrow2x=\dfrac{2}{3}+\dfrac{1}{2}=\dfrac{7}{6}\Leftrightarrow x=\dfrac{7}{6}:2=\dfrac{7}{12}\)

2x - 2/3 = 1/2

2x = 1/2 + 2/3 = 7/6

x = 7/6 : 2 = 7/12

vậy x = 7/12
