Let d = a * (b1 * c2 - c1 * b2) + b * (c1 * a2 - a1 * c2) + c * (a1 * b2 - b1 * a2)
Let d1 = m * (b1 * c2 - c1 * b2) + l * (c * b2 - b * c2) + k * (c1 * b - b1 * c)
Let d2 = m * (a2 * c1 - a1 * c2) + l * (c2 * a - c * a2) + k * (a1 * c - a * c1)
Let d3 = m * (a1 * b2 - b1 * a2) + l * (b * a2 - a * b2) + k * (a * b1 - b * a1)
Let x = d1 / d
Let y = d2 / d
Let z = d3 / d
