Step-by-step explanation:
x+2y= 5
or, x= 5-2y
The points of the above line are
(5,0) ; ( -1,3); ( 1,2); ( 3,1)
-x+y=4
or, y= 4+x
The points of the above line are,
(0,4);( 1,5); (2,6); (-1,3)
The solution of the system is the point of intersection of the two lines.
Here, these lines intersect at point ( -1,3)
The solution of the system is ( -1,3)
