Answer:


h<-15

Explanation:


-18+7h>12+9h

Add 18 to both sides:


-18+7h+18>12+9h+18


7h>9h+30

Subtract 9h from both sides:


7h>9h+30


-2h>30

Multiply both sides by -1 and flip the symbol:


\left(-2h\right)\left(-1\right)<30\left(-1\right)


2h<-30

Divide both sides by 2:


(2h)/(2)<(-30)/(2)


h<-15
