Step 1

1 of 5We wish to solve the following system of equations using the matrix method.

$\begin{align*}3x+3y+12z&=6\\ x+\phantom{1}y+\phantom{1}4z&=2\\ 2x+5y+20z&=10\\ -x+2y+\phantom{1}8z&=4 \end{align*}$

Step 1

1 of 2Solutions is

$x_1 = 0$

$x_2 = -4t + 2$

$x_3 = t$

As per the directions, use a software utility to solve the system of linear equations.
