Determine if the solutioir set for the system of equations shown is the empty set, contains one point or is infinite.
\[
\begin{array}{l}
x-y=5 \\
2 x+y=1
\end{array}
\]
0
1 solution
Infinite
\((2, -3)\)
Step 1 :\(\begin{cases} x-y=5\\ 2x+y=1 \end{cases}\)
Step 2 :\(\begin{cases} x-y=5\\ 2x+y=1 \end{cases} \Rightarrow \begin{cases} x=y+5\\ 2x+y=1 \end{cases}\)
Step 3 :\(\begin{cases} x=y+5\\ 2(y+5)+y=1 \end{cases} \Rightarrow y = -3\)
Step 4 :\(x = -3 + 5 \Rightarrow x = 2\)
Step 5 :\((2, -3)\)
