Question

Tìm tỉ số \(\frac{x}{y}\)biết rằng:

\(\frac{2x-y}{x+y}\)= \(\frac{2}{3}\)

Answer 1

\(\frac{2x-y}{x+y}=\frac{2}{3}\Rightarrow3\left(2x-y\right)=2\left(x+y\right)\)

                    \(\Rightarrow6x-3y=2x+2y\)

                   \(\Rightarrow6x-2x=3y+2y\)

                  \(\Rightarrow4x=5y\)

                  \(\Rightarrow\frac{x}{y}=\frac{5}{4}\)

Answer 2

\(\frac{2x-y}{x+y}=\frac{2}{3}\)

\(\Rightarrow3\left(2x-y\right)=2\left(x+y\right)\)

\(\Rightarrow6x-3y=2x+2y\)

\(\Rightarrow4x=5y\)

\(\Rightarrow\frac{x}{y}=\frac{4}{5}\)

Vậy.................
