3x - 2y = 1 . . . Pers. 1
- x + 5y = 4 . . . Pers. 2
3x - 2y = 1 (kali 5) 15x - 10y = 5
- x + 5y = 4 (kali 2) - 2x + 10y = 4
15x - 10y = 5
-2x + 10y = 8
___________ +
13x = 13
x = 1
3x - 2y = 1
- x + 5y = 4 (kali 3) - 3x + 15y = 12
3x - 2y = 1
- 3x + 15y = 12
____________ +
13y = 13
y = 1
Himpunan penyelesaian = {1, 1}
