Worksheet Worksheet 4
1.
Attempt to solve the system of equations using the method of elimination. Explain what happened and the conclusion that you can draw from it.
\begin{equation*}
\left\{ \begin{array} {rcrcr}
2x \amp + \amp 4y \amp = \amp 8 \\
-x \amp - \amp 2y \amp = \amp -4
\end{array} \right.
\end{equation*}
