Jawab:
Angsa + Kambing = 21 .................. (1)
Kaki angsa x jumlah angsa + Kaki kambing x jumlah kambing = 58
2 x Angsa + 4 x Kambing = 58
Angsa + 2 x Kambing = 29 .................. (2)
Dengan metode eliminasi Persamaan (1) dan (2), diperoleh:
Angsa + Kambing = 21
Angsa + 2 x Kambing = 29
____________________ -
- Kambing = -8
Kambing = 8 ekor
Substitusi ke Persamaan (1), diperoleh:
Angsa + 8 = 21
Angsa = 13 ekor (C)
