3x + 4y = -6 (x2)
2x - 3y = 13 (x3)
Dengan eliminasi x, dengan mengalikan dengan angka di atas, maka:
6x + 8y = -12
6x - 9y = 39
- - - Kurangi - - -
17y = -51
y = -3
Lalu,
Substitusikan untuk x
2x - 3y = 13
2x - 3(-3) = 13
2x + 9 = 13
2x = 4
x = 2
Sehingga,
x = 2 dan y = -3
2x-3y = 13 |x3|
6x + 8y = -12
6x - 9y = 39
17y = -51
y = -3
3x+4y = -6
3x+4.-3 = -6
3x-12 = -6
3x = 6
x = 2
