2 z - \frac{5}{z} = z - 6

\int \frac{{3 z}^{3} - 8 z + 5}{\sqrt{z^{2} - 4 z - 7}} d z = (z^{2} + a z + 36) \sqrt{z^{2} - 4 z - 7} + b ℓ n | z - 2 + \sqrt{z^{2} - 4 z - 7} | + C

z : \frac{4 z - 7}{3 - 2 z} = - 5

(x, y, z)

x + y + z = 6

x - y + z = 2

3 x + 2 y - 4 z = - 5

\frac{x}{4} = \frac{y}{2} = \frac{z}{1}

\frac{x - 4}{1} = \frac{y - 5}{4} = \frac{z - 9}{2}

\frac{x + 8}{4} = \frac{y + 6}{2} = \frac{z - 2}{1}
