himpunan penyelesaian 3x + 4y = 17, 5x +7y = 29 adalah

3x-17,5x=7y-4y=29
14,5x=3y=29
14,5x=29
x=29/14,5
3y=29
y=29/3

3x + 4y = 17 |5| 15x + 20y = 85
5x + 7y = 29 |3| 15x + 21y = 87
------------------------------------------ --
........................................ -y = -2 => y = 2
3x + 4y = 17
3x + 4(2) = 17
3x = 9
x = 3

HP = {(3, 2)}
