y = cokelat
Model Matematika
5x + 3y = 12.000
5x + 2y = 10.000
Metode Eliminasi
5x + 3y = 12.000
5x + 2y = 10.000
------------------------- -
y = 2.000
10x + 6y = 24.000
15x + 6y = 30.000
------------------------- -
5x = 6.000
x = 1.200
Jadi, harga sebuah permen Rp. 1.200 dan harga sebuah coklat Rp. 2.000
