Решите систему линейных уравнений геометрическим способом:

\(\displaystyle \begin{array}{rl} \left\{ \vphantom{\begin{aligned} 1\\ {\small \frac{2}{3}} \end{aligned}} \right.&\kern{-1.5em} \begin{aligned} {\small -\frac{4x}{7}}+3y&=5{\small , }\\ {\small \frac{6x}{7}}-8y&=-18 {\small .}\end{aligned} \end{array}\)

\(\displaystyle x=\)[ ] ,  \(\displaystyle y=\)[ ] .
