Graph the two equations. The result will be two lines that intersect. The ordered pair describing the point of intersection is the solution of the system.



Notice that the graphs cross at the point P(1,3). Also notice that the ordered pair (1,3) makes both equations true statements:


x+%2B+y+=+4 @ (1, 3) => 1+%2B+3+=+4
-x+%2B+y+=+2 @ (1, 3) => -1+%2B+3+=+2
