Question

What is the solution of the system? Use elimination.27x - y = 9-23x+y = 3

Answer 1

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:

`\begin{gathered} \begin{matrix}27x-y=9\end{matrix} \\ -23x+y=3 \\ ---------- \\ 4x=12 \\ (4x)/(4)=(12)/(4) \\ x=3 \\ \\ \end{gathered}`

2) Now, let's find the x variable by plugging into any of those equations the quantity of x:
