Apologizes. For elimination of linear equation what is X+Y=10 over -X+Y=4? What I got was (7,3), but the book says (3,7) for some odd reason.

The book is correct ( x, y) = ( 3,7)
The x value is always written first the y value second.
Explanation:
Now solve the resulting equation for y
put this value in for y in the first equation and solve for x
( x, y ) = ( 3, 7 )
The x value is written first and the y value second.
