Ta có :
\(\frac{x}{y}=\frac{3}{8}\Leftrightarrow\frac{x}{3}=\frac{y}{8}\)
Áp dụng tính chất dãy tỉ số bằng nhau ta có :
\(\frac{x}{3}=\frac{y}{8}=\frac{-3x-4y}{-3.3-4.8}=\frac{41}{-41}=\left(-1\right)\)
\(\Rightarrow\hept{\begin{cases}\frac{x}{3}=\left(-1\right)\Rightarrow x=\left(-3\right)\\\frac{y}{7}=\left(-1\right)\Rightarrow y=\left(-7\right)\end{cases}}\)
Vậy ...
