x= buku
y= pensil
3x + 2y= 4.500 | dikali 2 |
2x + 4y= 4.000 | dikali 3 |
mencari nilai y :
6x + 4y= 9.000
6x + 12y= 12.000 _
-8y= -3.000
y= -3.000/-8
y= 375
Jadi, harga 1 buah pensil adalah Rp375,00.
2b + 4p = Rp 4.000 | x 3 | ⇒ 6b + 12p = Rp 12.000 -
-8p = Rp -3.000
p = Rp 375
Jadi, harga satu buah pensil adalah Rp 375.
