Решите систему уравнений
$\begin{equation*}
\begin{cases}
\frac{3x - 2}{4y + 3} = \frac{4}{15}, &\\
\frac{5x - y}{3y - 2} = 1. &
\end{cases}
\end{equation*}$
$\begin{equation*}
\begin{cases}
\frac{3x - 2}{4y + 3} = \frac{4}{15} &\\
\frac{5x - y}{3y - 2} = 1 &
\end{cases}
\end{equation*}$
$\begin{equation*}
\begin{cases}
15(3x - 2) = 4(4y + 3) &\\
5x - y = 3y - 2 &
\end{cases}
\end{equation*}$
$\begin{equation*}
\begin{cases}
45x - 30 = 16y + 12 &\\
5x - y = 3y - 2 &
\end{cases}
\end{equation*}$
$\begin{equation*}
\begin{cases}
45x - 16y = 30 + 12 &\\
5x - y - 3y = -2 &
\end{cases}
\end{equation*}$
$\begin{equation*}
\begin{cases}
45x - 16y = 42 &\\
5x - 4y = -2 | * (-4) &
\end{cases}
\end{equation*}$
$\begin{equation*}
\begin{cases}
45x - 16y = 42 &\\
-20x + 16y = 8 &
\end{cases}
\end{equation*}$
45x − 16y − 20x + 16y = 42 + 8
25x = 50
x = 50 : 25
x = 2
5x − 4y = −2
4y = 5x + 2
4y = 5 * 2 + 2
4y = 10 + 2
4y = 12
y = 12 : 4
y = 3
