we have
-------> inequality 
-------> inequality 
using a graph tool
see the the attached figure N 
the solution of the system is the shaded area

This point satisfies the inequality
but does not satisfy the inequality
.
therefore
it is not a solution of the system
see the attached figure N 
inequality 


-----> is not true
inequality 


-----> is true

This point satisfies the inequality
but does not satisfy the inequality
.
therefore
it is not a solution of the system
see the attached figure N 
inequality 


-----> is not true
inequality 


-----> is true

This point satisfies the inequality
but does not satisfy the inequality
.
therefore
it is not a solution of the system
see the attached figure N 
inequality 


-----> is not true
inequality 


-----> is true

This point satisfies the inequality
and satisfies the inequality
.
therefore
it is a solution of the system
see the attached figure N 
inequality 


-----> is true
inequality 


-----> is true

This point satisfies the inequality
but does not satisfy the inequality
.
therefore
it not a solution of the system
see the attached figure N 
inequality 


-----> is true
inequality 


-----> is not true

This point satisfies the inequality
and satisfies the inequality
.
therefore
it is a solution of the system
see the attached figure N 
inequality 


-----> is true
inequality 


-----> is true
therefore
the answer is
