8x appears in both equations so it can be eliminated and y can be found by substituting for 8x: 9-5y-3y=-31. Adding 31 to both sides: 40-8y=0, so 8y=40 and y=5. 8x=9-5y=9-25=-16, so x=-2. The ordered pair (x,y) is therefore (-2,5). This represents the point where the lines, represented by the two equations, intersect.
