If x, y and z are Integers and z is not equal to 0, Find range of
$$\frac{\left(x+y\right)}{z}$$
$$-2<z<2$$
$$-5<x<10$$
$$-11<y<4$$

$$\left(A\right)-8<\frac{\left(x+y\right)}{z}<7$$
$$\left(B\right)8<\frac{\left(x+y\right)}{z}<-7$$
$$\left(C\right)-16<\frac{\left(x+y\right)}{z}<14$$
$$\left(D\right)-14<\frac{\left(x+y\right)}{z}<14$$
$$\left(E\right)-16<\frac{\left(x+y\right)}{z}<16$$

The OA is E.

I need help with this PS question. Can any expert explain it please? Thanks.
