Step by Step equation on Matrix

3x -y - z = 4
x + y + 2z = 1
4x - y + z = 0

Do you just want to solve this 3 x 3 linear system or must it be done using matrices?
The coefficients are such that elimination will probably be quite easy:
add the first and third equation and add twice the first equation to the second; that will  eliminate z.  Go from there.
