Задание

Дана система линейных уравнений:

\(\displaystyle \left\{ \begin{aligned} {\small \frac{5}{3}}v+{\small \frac{8}{3}}u=&7{\small , }\\ 9v-13u=&10{\small . } \end{aligned} \right. \)

Умножьте первое уравнение на \(\displaystyle 9{\small : }\)

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[5px] 1 \end{aligned}} \right. \)
[ ]\(\displaystyle =\)[ ]\(\displaystyle {\small , }\)
\(\displaystyle 9v-13u=10{\small . }\)
