Berapa HP dari PLDV di bawah
X – 3y = 2 dan 3x + 5y =-1
Jawaban:
HP = {1/2,-1/2}
Penjelasan dengan langkah-langkah:
x – 3y = 2 |3| 3x-9y = 6
3x + 5y = -1 |1| 3x+5y = -1
————– (-)
– 14y = 7
y = 7/-14
y = -1/2
sub y = -1/2
x – 3y = 2
x – 3(-1/2) = 2
x – (-3/2) = 2
x + (3/2) = 2
x = 2 – 3/2
x = 1/2
HP = {x,y} = {1/2,-1/2}
