Find the value of $x, y$ and $z$ from the given linear equations: $x + y + z = 0, 2 x + 5 y + 7 z = 0, 2 x - 5 y + 3 z = 0$

\frac{log 3}{x - y} = \frac{log 5}{y - z} = \frac{log 7}{z - x}

3^{x + y} \cdot 5^{y + z} \cdot 7^{z + x}

L_{1} : \frac{x - 1}{2} = \frac{y}{- 2} = \frac{z + 2}{- 1}

L_{2} : \frac{x + 3}{8} = \frac{y - 4}{1} = \frac{z}{- 4}
