Solutions for equations involving X :
$\displaystyle \quad\quad 4 x - 6 = 0\quad \Rightarrow \quad X = \left [ \frac{3}{2}\right ]$
$\displaystyle \quad\quad x^{2} - 9 = 0\quad \Rightarrow \quad X = \left [ -3, \quad 3\right ]$ 
Solutions for equations involving Y :
$\displaystyle \quad\quad \sin{\left (y \right )} = 0\quad \Rightarrow \quad Y = \left [ 0, \quad \pi\right ]$
