\[\left\{ \begin{matrix} y - x = 0\ \ \\ 3x - y = 4 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ \ }\left\{ \begin{matrix} y = x\ \ \ \ \ \ \ \ \ \ \ \\ y = 3x - 4 \\ \end{matrix} \right.\ \]
\[y = x\]
\[x\] | \[0\] | \[1\] |
---|---|---|
\[y\] | \[0\] | \[1\] |
\[y = 3x - 4\]
\[x\] | \[0\] | \[1\] |
---|---|---|
\[y\] | \[- 4\] | \[- 1\] |
