Question

tìm x biết

a,\(\frac{x}{3}=\frac{y}{5}vày-x=8\)8

Answer 1

\(\frac{x}{3}=\frac{y}{5}=\frac{y-x}{5-3}=\frac{8}{2}=4\)

\(\frac{x}{3}=4\Rightarrow x=12\)

\(\frac{y}{5}=4\Rightarrow y=20.\)

Answer 2

\(\frac{x}{3}=\frac{y}{5}=\frac{y-x}{5-3}=\frac{88}{2}=44\)

\(\frac{x}{3}=44\Rightarrow x=132\)

\(\frac{y}{5}=44\Rightarrow y=220.\)
