3x + 2y = 12
x + 2y = 4 - (dikurangi)
⇔ 2x = 8
x = 8/2
x = 4
- Substitusi sembunyi "x"
3x + 2y = 12 (dikali 1)
x + 2y = 4 (dikali 3)
3x + 2y = 12
3x + 6y = 12 - (dikurangi)
⇔-4y = 0
y = 0/-4
y = 0
∴ HP : {4,0}
ket : -HP = Himpunan Penyelesaian
mis: x=0
jadi,3(0)+2y=12
2y=12
y=6
mis: y=0
jadi, 3x+2(0)=12
3x=12
x=4
hp{x,y} => hp{4,6}
2. x+2y=4
mis: x=0
jadi, 0+2y=4
2y=4
y=2
mis: y=0
jadi, x+2(0)=4
x=4
hp{x,y} => hp{4,2}
