X + (1/2)y = 5 → 2x + y = 10 ………………(1)
(1/4)x + (1/2)y = 2 → x + 2y = 8 …………..(2)
eliminasi (1) dan (2)
4x + 2y = 20
x + 2y = 8
——————- (-)
3x = 12
x = 4
subtitusi
x + 2y = 8
4 + 2y = 8
2y = 4
y = 2
jadi
HP = {(4,2)}
X + (1/2)y = 5 → 2x + y = 10
(1/4)x + (1/2)y = 2 → x + 2y = 8
eliminasi :
4x + 2y = 20
x + 2y = 8
3x = 12
x = 4
subtitusi
x + 2y = 8
4 + 2y = 8
2y = 4
y = 2
HP = {(4,2)}
