the correct question is
The midpoint of kl is m(–8, 1). one endpoint is k(–6, 5). find the coordinates of the other endpoint l.
we know that
the formula of midpoint is
Xm=(x1+x2)/2----> 2*Xm=x1+x2------> x2=2*Xm-x1
Ym=(y1+y2)/2----> 2*Ym=y1+y2------> y2=2*Ym-y1
let
(x1,y1)-------> (–6, 5).
(Xm,Ym)-----> (-8,1)
find (x2,y2)
x2=2*Xm-x1-----> 2*(-8)-(-6)----> -10
 y2=2*Ym-y1----> 2*(1)-5-----> -3
the point l is (-10,-3)
 
        
             
        
        
        
Once your friend has thought of a number, do the following: 
1. Ask him or her to multiply the chosen number by 2.
2.Choose an even number to use yourself. Ask your friend to add this number to the one in his head.
3.Tell him/her to divide the new number by 2.
4.Tell your friend to subtract his original number from the equation.
5."Guess" the number.

ANSWER
No solution
EXPLANATION
The first equation is 

and the second equation is 

We equate the two equations to obtain;

This implies that


There is no real number whose square is -1.
Therefore, the equation has no solution.
