I suppose the answer is b. Graph the system to show all possible solutions
        
             
        
        
        

change 

given you

{ }
}
also given

change the operation sign to =



dividing through by -4


so the truth set is
{x:x>9/4}.
The < sign changes to > because we divided by a negative number when solving for x
