x - 4/9 = 1/2 + 1/3

x - 4/9 = 5/6

x = 5/6 + 4/9

x = 23/18

vậy x = ...

\(x-\dfrac{4}{9}=\dfrac{1}{2}+\dfrac{1}{3}\)

\(x-\dfrac{4}{9}=\dfrac{5}{6}\)

\(x=\dfrac{5}{6}+\dfrac{4}{9}=\dfrac{15}{18}+\dfrac{8}{18}\)

\(x=\dfrac{23}{18}\)

\(x-\dfrac{4}{9}=\dfrac{1}{2}+\dfrac{1}{3}\)

\(x-\dfrac{4}{9}=\dfrac{5}{6}\)

       \(x=\dfrac{23}{18}\)
