p M = p'
p = p' M⁻¹
p = (-5, 20) . 1/(-4 . 0 - 2 . (-5)) . (0  5}
                                                   (-2 4)
p = (-5, 20) . (1/10) (0   5)
                               (-2  4)

p = (-5, 20) . (0       1/2)
                     (-1/5   2/5)

p = (-5 . 0 + (-1/5 . 20)), (-5 . 1/2 + 2/5 . 20))
p = (-4, 11/2)
