The first equation can be solved algebraically,
$$3(x – 7) \geq 9$$

or$$x - 7 \geq 3$$

or $$x \geq 10$$

For 2nd equation:

$$0.25y – 3 \leq 1$$

or $$0.25y \leq 4$$

or $$y\leq 16$$

So we cannot reach to a definite solution for this because x can be of any value from 10 and y can be any value less than or equal to 16

So option is D
