Answer:
x = -2
Step-by-step explanation:
Arrange 6x + y= -5, -6x + 12y=96 vertically:
 6x + y= -5
-6x + 12y=96       Now combine like terms:
--------------------
        13y = 91
Solving for y by dividing both sides by 13:  y = 7
Find x by substituting 7 for y in the second equation:  -6x + 12(7) = 96
Then -6x = -84 + 96, or:
-6x = 12, and so x = -2
 
        
             
        
        
        
The ordered pairs already plotted have x-coordinates: -3, -2, 1, and 2.
A function cannot have two ordered pairs with the same x-coordinate.
The answer cannot have -3, -2, 1, or 2 as the x-coordinate.
