An open circle means not equal to. So, if your equation is x < 4, You would put an OPEN circle at four because it can't equal four.
        
             
        
        
        
Answer:
x = 
Step-by-step explanation:
<u>To solve quadratic systems,we always substitute one variable in terms if the other and then solve the equation.</u>
x + 2y = 6                                 ---------------(1)
y - 5 =  ---------------(2)
         ---------------(2)
y =  + 5         ---------------(3)
 + 5         ---------------(3)
Substitute (3) in (1) ,
x + 2(  + 5 ) = 6
 + 5 ) = 6
 =
 =
x + 2(  + 5 ) = 6
 + 5 ) = 6
 --------------(4)
      --------------(4)
The roots of the quadratic equation  is
 is
x =  -----------(5)
   -----------(5)
According to equation (5),solution of (4) is
x =  
x =  
x =
