Дана система линейных уравнений:

\(\displaystyle \begin{array}{rl} \left\{ \vphantom{\begin{aligned} 1\\ {\small \frac{2}{3}} \end{aligned}} \right.&\kern{-1.5em} \begin{aligned} {\small \frac{3}{4}}v-{\small \frac{9}{4}}u=&{\small \frac{1}{4}},\\ {\small \frac{5}{6}}v+{\small \frac{7}{6}}u=&{\small \frac{13}{6}} {\small .}\end{aligned} \end{array}\)

Умножьте первое уравнение на \(\displaystyle 4,\) а второе на \(\displaystyle 6{\small : }\)

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[5px] 1 \end{aligned}} \right. \)	[ ]\(\displaystyle =\)[ ],
	[ ]\(\displaystyle =\)[ ].
