Himpunan penyelesain persamaan linear 2x+4y=8 dan 5x+2y=16 adalah

2x + 4y = 8 (×1)  2x + 4y = 8
5x + 2y = 16 (×2) 10x + 4y = 32
___________________________ -
                     -8x = -24
                        x = 3

2x + 4y = 8
2(3) + 4y = 8
4y = 2
y = 1/2

HP = {3,1/2)

2x + 4y = 8 (×5) 10x + 20y = 40
5x + 2y = 16 (×2) 10x + 4y = 32
___________________________ -
                               16y = 8
                                   y = 8/16
                                   y = 1/2

2x + 4y = 8
2x + (4 . 1/2) = 8
2x + 2 = 8
2x = 8 - 2
2x = 6
x = 6/2
x = 3

Himpunan penyelesaian = {x,y} = {3,1/2}
