x +5z=0
5x+y =0
y-3z=0
-------
x + 0 + 5z = 0
5x+ y + 0 = 0
0 + y - 3z = 0
------
Subtract 5 times row1 from row2 to get:
x + 0 + 5z = 0
0 + y - 25z= 0
0 + y - 3z = 0
-----
Subtract 2nd row from 3rd row to get:
x + 0 + 5z = 0
0 + y - 25z= 0
0 + 0 + 22z = 0
-----
Solve the 3rd row for "z":
z = 0
----
Solve the 2nd row for "y":
y = 0
----
Solve for "z"
z = 0
