Show that the solution set of the following linear inequations is empty set:

(i) $x - 2 y \geq 0, 2 x - y \leq - 2, x \geq 0, y \geq 0$

(ii) $x + 2 y \leq 3, 3 x + 4 y \geq 12, y \geq 1, x \geq 0 a n d y \geq 0$

z = 5 x + 2 y

x - 2 y \leq 2

3 x + 2 y \leq 12

- 3 x + 2 y \leq 3

x \geq 0, y \geq 0

- 2 x = 4 y + 6
