Linear Algebra Examples

A = ⎡ ⎢ ⎣ \begin{matrix} - 3 & 2 & 1 4 & - 4 & 4 1 & 2 & 3 \end{matrix} ⎤ ⎥ ⎦

$A = [\begin{array}{c} - 3 & 2 & 1 \\ 4 & - 4 & 4 \\ 1 & 2 & 3 \end{array}]$

Step 1

Write the matrix as a system of linear equations.

- 3 x + 2 y = 1

$- 3 x + 2 y = 1$

4 x - 4 y = 4

$4 x - 4 y = 4$

x + 2 y = 3

$x + 2 y = 3$
