[tex]\dfrac{15}{x}=\dfrac{10}{y}=\dfrac{30}{18}[/tex]
[tex]\dfrac{15}{x}=\dfrac{30}{18} \Longrightarrow x = \dfrac{15 \cdot 18}{30} = 9[/tex]
Analog se determina y.

Pai faci asa 15 dupra x , 10 supra y si 30 supra 18
Apoi afli y ( y30=180=>y=6)
Dupa 10x=90(15 ori 6)=>x =9
Apoi afli y ( y30=180=>y=6)
Dupa 10x=90(15 ori 6)=>x =9
