kambing dimisalkan y
2x+4y = 272
x + y = 100 (X2)
menjadi
2x+4y =272
2x+2y = 200 (masing-masing dikurangi
-> 2y = 72
y = 36 kambing
disubtitusikan x+y = 100 ->x+36 = 100 -> x=64
jadi itik = 64 dan kambing = 36
semoga membantu:)
dan kambing = y
jadi x+y=100
dan 2x+4y=272
2x + 2y = 200
2x + 4y = 272
---------------------- ----
-2y= - 72
y= 36
x= 64
jadi bebek ada 64 dan kambing ada 36
