Question

Tìm X 

(X+5/9)x2/3=2/5

Answer 1

\(\left(x+\dfrac{5}{9}\right)\)x\(\dfrac{2}{3}\)=\(\dfrac{2}{5}\)

\(\left(x+\dfrac{5}{9}\right)\)= \(\dfrac{2}{5}\):\(\dfrac{2}{3}\)

\(\left(x+\dfrac{5}{9}\right)\)=\(\dfrac{3}{5}\)

=> \(x\)= \(\dfrac{3}{5}-\dfrac{5}{9}=>x=\dfrac{2}{45}\)

Answer 2

(x+5/9).2/3=2/5

x+5/9 = 2/5:2/3

x+5/9=3/5

x=3/5-5/9

x=2/45

Vậy x=2/45

Answer 3

(x+5/9).2/3=2/5

x+5/9 = 2/5:2/3

x+5/9=3/5

x=3/5-5/9

x=2/45

Vậy x=2/45
