Suppose the midpoint of XY is M ;

So ;

[tex] \frac{x + y}{2} = m \\ [/tex]

Multiply sides by 2

[tex]x + y = 2m[/tex]

( x , y ) + ( 4 , - 8 ) = ( 2 × 3 , 2 × -5 )

( x , y ) + ( 4 , - 8 ) = ( 6 , -10 )

( x , y ) = ( 6 , -10 ) - ( 4 , - 8 )

( x , y ) = ( 6 - 4 , -10 + 8 )

( x , y ) = ( 2 , - 2 )

So the coordinates of the point X is :

X = ( 2 , - 2 )

And we're done.....
