\[\left\{ \begin{matrix} x + y = 3\ \ \\ 2x - y = 3 \\ \end{matrix} \right.\ \Longrightarrow \left\{ \begin{matrix} y = 3 - x\ \ \\ y = 2x - 3 \\ \end{matrix} \right.\ \]
\[y = 3 - x\]
\[x\] | \[0\] | \[1\] |
---|---|---|
\[y\] | \[3\] | \[2\] |
\[y = 2x - 3\]
\[x\] | \[0\] | \[1\] |
---|---|---|
\[y\] | \[- 3\] | \[- 1\] |
