Answer:
12.058
Step-by-step explanation:
 You steal one "count" from the 8, and move it to the 7 so you have 12.0587, instead of 12.0578. Then, you are able to take off the 7 from the back. 
 
        
                    
             
        
        
        
For any point to be in the first quadrant, it must have a positive "x" value and "y" value.  
If x = 1 then y = 2, a point with both x and y positive values which would be in the First Quadrant.
        
             
        
        
        
2.8
-14x+28=-4x
10x=28
X=2.8
