Cari eleminasi dan subtitusi :
5x – 3y = -13
2x + 7y=3

[5x-3y=-13]x 2= 10x-6y=-26……1
[2x+7y=3]x5= 10x+35y=15…….2
perrmisalan 1-2
-41y=-41
y=1
substitusikan y=1 ke 5x-3y=-13
5x-3=-13
5x=-10
x=-2
dan y=1

5x-3y=-13[x2]
2x+7y= 3 [x5]
10x -6y= -26 – 10x+35y=15
-41y = -41
y=1
2x+7y= 3
2x+7.1= 3
2x +7 = 3
2x = 3-7
2x= -4
x= 2
