Задание
Дана система линейных уравнений:
\(\displaystyle \begin{array}{rl} \left\{ \vphantom{\begin{aligned} 1\\ {\small \frac{2}{3}} \end{aligned}} \right.&\kern{-1.5em} \begin{aligned} {\small \frac{7}{5}}s-{\small \frac{6}{5}}t=&9,\\ {\small \frac{3}{11}}s+{\small \frac{4}{11}}t=&{\small \frac{2}{11}} {\small .}\end{aligned} \end{array}\)
Умножьте первое уравнение на \(\displaystyle 5,\) а второе на \(\displaystyle 11{\small : }\)
