Question

X, Y, Z are three elements, which undergo chemical changes according to the following equation:
I: $X_{2} O_{3} + 2 Y \to Y_{2} O_{3} + 2 X$
II: $Y_{2} O_{3} + 3 Z \to 3 Z O + 2 Y$
The order of increasing reactivity is:

X < Y < Z

x - 2 y + z = 0

y - z = 2

2 x - 3 z = 10

\frac{2 x - 3 y}{3 z + y} = \frac{z - y}{z - x} = \frac{x + 3 z}{2 y - 3 x}

= \frac{x}{y}
