◼ Gunakan Metode Eliminasi
5m + 7k = 12 → Kali 3
-3m + 6k = 3 → Kali 5
------------------
15m + 21k = 36
-15m + 30k = 15
------------------------ +
51k = 51
k = 51/51
k = 1
◼ Tentukan Nilai m
5m + 7k = 12
5m + 7(1) = 12
5m + 7 = 12
5m = 12 - 7
5m = 5
m = 5/5
m = 1
Jadi, Himpunan Penyelesaian :
m = 1
k = 1
