Step 1
Write the augmented matrix of the following system of equations.
8x+4y+2=0
4x-8y-6=0
Step 2
Rewrite the given equations
8x+4y=-2
4x-8y=6
AX=b
$\left[\begin{array}{cc}8& 4\\ 4& -8\end{array}\right]\left[\begin{array}{c}x\\ y\end{array}\right]=\left[\begin{array}{c}-2\\ 6\end{array}\right]$
Step 3
Augmented matrix of the given system of equations
$\left[A:b\right]=\left[\begin{array}{ccc}8& 4& -2\\ 4& -8& 6\end{array}\right]$
