Question

System A System B 3x 2y = 4 5x 8y = -1 5ar 8y = -1 Zr - 2y = 4 1) How can we get System from System /? are the systems equivalent?

Answer 1

System A:

$\begin{gathered} -3x-2y=4_{\text{ }} \\ 5x-8y=-1 \end{gathered}$

If we change the order of the equations we can get system B:

$\begin{gathered} 5x-8y=-1 \\ -3x-2y=4 \end{gathered}$
