harga 2 flashdisk dan 3 memory card adalah Rp230.000,00, sedangkan harga 3 flashdisk dan 2 memory adalah Rp220.000,00. harga 4 flashdisk dan 5 memory card adala

flashdisk = f
memory card = m
2f + 3m = 230
3f + 2m = 220
f dihilangkan dulu dikali 3 dan 2
6f + 9m = 690
6f + 4m = 440
___________-
5m = 250
m = 50
2f + 3.50 = 230
2f = 230 - 150
f = 40
4f + 5m = 4.40 + 5.50 = Rp. 410.000

harga flashdisk 1=40.000
memory card =50.00
((2*40=80.000)+(3*50=150.000))=230
3*40=120.000+2*50.000=100.000=250.000
jawab:
4*40.000=160.000(fashdisk)
5*50.000=250.000(memori card)
160.000+250.000=410.000
