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

\(\displaystyle{\left[\begin{array}{cc} {8}&{4}\\{4}&-{8}\end{array}\right]}{\left[\begin{array}{c} {x}\\{y}\end{array}\right]}={\left[\begin{array}{c} -{2}\\{6}\end{array}\right]}\)

Step 3

Augmented matrix of the given system of equations

\(\displaystyle{\left[{A}:{b}\right]}={\left[\begin{array}{cc|c} {8}&{4}&-{2}\\{4}&-{8}&{6}\end{array}\right]}\)
