Determine whether the planes are parallel, octagonal or neither
Hi, if you could explain to me how to do the questions below so that I can finish the rest that I have that would be really helpful. Thanks!
4x + 5y + z = -1
3x + 5y - 37z = -3
2x - y - 3x = -5
-2x - 6y - z = 6
5x - 2y - 4z = 6
-15x + 6y + 12z = -16
