1) In this system, let's solve it with the Elimination Method. We can begin by getting rid of the y-variables by adding those equations simultaneously:
[tex]\begin{gathered} \begin{matrix}27x-y=9\end{matrix} \\ -23x+y=3 \\ ---------- \\ 4x=12 \\ \frac{4x}{4}=\frac{12}{4} \\ x=3 \\ \\ \end{gathered}[/tex]2) Now, let's find the x variable by plugging into any of those equations the quantity of x:
