Question

\(\dfrac{x}{y}\)=\(\dfrac{3}{5}\) và y - x=6

Answer 1

Ta có: \(\dfrac{x}{y}\)=\(\dfrac{3}{5}\) và y-x=6

=>\(\dfrac{x}{3}=\dfrac{y}{5}\)

=>\(\dfrac{x}{3}=\dfrac{y}{5}=\dfrac{y-x}{5-3}=\dfrac{6}{2}=3\)

Vậy x=3*3=9

       y=5*3=15

Answer 2

x/y=3/5

=>x/3=y/5

=>x/3=y/5=y-x/5-3=3

x=3x3=9

y=5x3=15
