Ta có: \(\frac{3}{x}=\frac{y}{35}=\frac{-36}{84}=\frac{-3}{7}\)
\(\Rightarrow\frac{3}{x}=\frac{-3}{7}\Rightarrow x=-7\)
\(\Rightarrow\frac{y}{35}=\frac{-3}{7}\)
\(\Rightarrow\frac{y}{35}=\frac{-15}{35}\Rightarrow y=-15\)
Vậy x = -7; y = -15
Ta có:
\(\frac{3}{x}=\frac{y}{35}=\frac{-36}{84}=\frac{-3}{7}\)
Ta có:
\(\frac{3}{x}=\frac{-3}{7}\\ =>x=\frac{3.7}{-3}=-7\)
Ta lại có:
\(\frac{y}{35}=\frac{-3}{7}\\ =>y=\frac{-3.35}{7}=-15\)
\(Vậy:x=-7;y=-15\)
Mình làm chi tiết hơn nè.
