X+y= 10.............(i) X-y= 4................(ii) Taking I X + y = 10 X =10-y Let, y=5 So, x=10-y X=10-5 X=5 Let, y =4 So, x=10-4 X=6 Let y =6 So, x=10-6 X=4 Now taking equation. (ii) X-y=4 X=4+y Let ,y=1 So, x=4+1 X=5 Let, y=0 So, x=4+0 X=4 Let, y =2 So, x=4+2 X=6 Here the coordinates for equation (i) are A(5,5) ;B(6,4) ; C(4,6) Here the coordinates for equation (ii)are A(5,1);B(4,0);C(6,2). Draw the coordinates on graph . I cannot send the pic of graph.
