Question

\(\dfrac{11}{10}.x-\dfrac{1}{3}=\dfrac{2}{5}\)

Answer 1

=>11/10x=2/5+1/3=6/15+5/15=11/15

nên x=2/3

Answer 2

\(\dfrac{11}{10}.x-\dfrac{1}{3}=\dfrac{2}{5}\)

\(\dfrac{11}{10}.x=\dfrac{2}{5}+\dfrac{1}{3}\)

\(\dfrac{11}{10}.x=\dfrac{11}{15}\)

      \(x=\dfrac{11}{15}:\dfrac{11}{10}\)

      \(x=\dfrac{2}{3}\)

vậy x=...

Answer 3

11/10.X-1/3=2/5

11/10.X=2/5+1/3

11/10.X=11/15

X=11/15:11/10

X=2/3

Answer 4

⇔\(\dfrac{11}{10}\)x=\(\dfrac{2}{5}\)+\(\dfrac{1}{3}\)

⇔\(\dfrac{11}{10}\)x=\(\dfrac{11}{15}\)

⇔x=\(\dfrac{11}{15}\):\(\dfrac{11}{10}\)

⇔x=\(\dfrac{3}{2}\)
