1) Перепишем первую систему уравнений в новой форме:\[
\begin{cases}
x + 2y = 5 \\
3x - y = 7
\end{cases}
\]
2) Преобразуем вторую систему уравнений соответственно:
\[
\begin{cases}
2x - y = 3 \\
4x + 5y = 9
\end{cases}
\]
3) Переформулируем третью систему уравнений:
\[
\begin{cases}
x + y = 4 \\
2x - 3y = 1
\end{cases}
\]
