Worksheet Worksheet 5
1.
Solve the system of equations using the method of elimination.
\begin{equation*}
\left\{ \begin{array} {rcrcr}
ax \amp + \amp by \amp = \amp c \\
dx \amp + \amp ey \amp = \amp f
\end{array} \right.
\end{equation*}
2.
Use the formula you derived from the previous problem to solve the system of equations. Do you find it easier to use the formula or to use the method of elimination?
\begin{equation*}
\left\{ \begin{array} {rcrcr}
-2x \amp + \amp 3y \amp = \amp 5 \\
3x \amp - \amp 5y \amp = \amp -6
\end{array} \right.
\end{equation*}
