2x - 3y = 13 (dikalikan 3)
Maka:
6x + 8y = -12
6x - 9y = 39
(dikurangkan)
Hasilnya:
17 y = -51
y = -51/17
y = -3
Mencari nilai x :
3x + 4y = -6 (dikalikan 3)
2x - 3y = 13 (dikalikan 4)
hasilnya:
9x + 12y = -18
8x - 12y = 52
(ditambahkan)
maka didapat:
17x = 34
x = 2
Jadi, diperoleh x = 2 dan y = -3
