himpunan penyelesaian persamaan 2x + y =10 untuk x,y€ { bilangan cacah } adalah,.

2x + y = 10, untuk x,y € cacah
x = 0 ==> 2.0+ y = 10==> y = 10
x = 1 ==> 2.1 + y = 10 ==> y = 8
x = 2 ==> 2.2 +y = 10 ==> y = 6
x = 3 ==> 2.3+y = 10 ==> y = 4
x = 4 ==> 2.4 +y = 10 ==> y = 2
x = 5 ==> 2.5 +y = 10 ==> y = 0
x = 6 ==> 2.6+y = 10 ==> y = -2 (tidak dipakai karena x, y € cacah)
HP = { (0,10),(1,8),(2,6),(3,4),(4,2),(5,0) }
