\[\left\{ \begin{matrix} x - y = 1\ \ \ \ \ \\ 2x - 2y = 3 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} y = x - 1\ \ \\ y = \frac{2x - 3}{2} \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} y = x - 1\ \ \ \\ y = x - 1,5 \\ \end{matrix} \right.\ \]

\[y = x - 1\]

\[x\]	\[0\]	\[1\]
\[y\]	\[- 1\]	\[0\]

\[y = x - 1,5\]

\[x\]	\[0\]	\[3\]
\[y\]	\[- 1,5\]	\[1,5\]

\[Ответ:нет\ решений.\ \]
