jawab yg bner dapet banyak poin, klo ngasal ( serius ) gw report ! hahaha... Pakai cara ya kak makasih.

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)}
