Solving (1),

The second inequality,

has solutions,

Combining these solutions together (find their intersection in strict terms) and you have,

Solving (2),

has solutions,

Combining these solutions together (find their intersection in strict terms) and you have,

(cuz first inequlaity is contained in this one).

Thus,
