Maaf Kalau Salah
Verified answer
1.) x + 5y = -5 dan x + y + 5 = 0x = -y - 5
subtitusikan x ke
x + 5y = -5
-y - 5 + 5y = -5
4y = -5 + 5
4y = 0
subtitusikan y = 0 ke
x + 5y = -5
x + 0 = -5
x = -5
jadi HP : {(-5,0)}
2.) x + y = 12 dan 3x - y = 4
y = 3x - 4
subtitusikan y ke
x + y = 12
x + 3x - 4 = 12
4x = 12 + 4
4x = 16
x = 16/4
x = 4
subtitusikan x = 4 ke
x + y = 12
4 + y = 12
y = 12 - 4
y = 8
jadi
HP : {(4,8)}
