Union of solutions

I need to build a script in which i have to calculate the union solutions for some equations.

For example:

18 - Kp > 0
6Kp + 72 > 0

In matlab code:

>> syms kp
>> solve('18-kp>0')

ans =

Dom::Interval(-Inf, 18)
>> solve('6*kp+72>0')
ans =

Dom::Interval(-12, Inf)

I know that the union of the solution is (-12, 18) but how do i write in matlab? Thank you!
