2k + 1s = 8.200.000       dikalikan 2
3k + 2s = 14,400.000                    1
                                                           4k + 2s = 16.4000.000
                                                           3k + 2s = 14.400.0000 
                                                                  [ dikurangi ]
                                                             1k = 2.000.0000
2k + 1s = 8.200.000
2 × 2.000.000 + 1s = 8.200.000
4.000.000 + 1s = 8.2000.000
                    1s = 8.2000.000 - 4.000.000
                    1s = 4.2000.000

Jadi harga 1 ekor kambing = 2 juta
                         1 ekor sapi = 4 juta 200
