Step-by-step explanation:
 
        
             
        
        
        
we have
 ------> inequality A
The solution of the inequality A is the shaded area below the solid red line
see the attached figure N      
 ------> inequality B
The solution of the inequality B is the shaded area above the dotted blue line
see the attached figure N  
therefore
The solution of the system of inequalities is the shaded area between the solid red line and the dotted blue line
see the attached figure N  
therefore
the answer in the attached figure N
