Дана система линейных уравнений:

\(\displaystyle \begin{array}{rl} \left\{ \vphantom{\begin{aligned} 1\\ {\small \frac{2}{3}} \end{aligned}} \right.&\kern{-1.5em} \begin{aligned} {\small \frac{1}{2}}x+{\small \frac{25}{2}}y=&{\small -\frac{9}{2}},\\ {\small \frac{3}{8}}x+{\small \frac{5}{8}}y=&{\small \frac{17}{8}} {\small .}\end{aligned} \end{array}\)

Умножьте первое уравнение на \(\displaystyle 2,\) а второе на \(\displaystyle 8{\small : }\)

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