5m+2n=40.000 dan 8m+5n=68.500 buat dalam bentuk eliminasi

Leonych = 8m + 5n = 68.500 - 5m + 2n = 40.000
= 8m + 5n = 68.500 - 5m - 2n = -40.000
= 3m + 3n = 28.500 / = 3mn = 28.500

Prajnaparamitta $5m+2n=40.000 \\ 8m+5n=68.500 \\ \\ b.eliminasi: \\ 5m+2n=40.000 (dikali8) \\ 8m+5n=68.500 (dikali 5) \\ \\ 40m+16n = 320.000 \\ {40m+25n=342.500} \\ (dikurang) \\ hasilnya:\\ {-9n=-22.500} \\ n=2500 \\ \\ 5m+2n=40.000 \\ (dimasukkan n nya) \\ 5m+2(2500)=40.000 \\ 5m+5000=40.000 \\ 5m=40.000/5000 \\ 5m=8 \\ m= \frac{8}{5}$

semoga membantu
