samakan salah satu koefisien variable nya, misal koefisien x :
2x + 3y = 43x + 5y = 8
menjadi
6x + 9y = 126x + 10y = 16
-> -y = -4 , maka y = 4
masukkan nilai y ke salah satu persamaan, misalnya persamaan pertama :
2x + 3y = 4
2x + 3(4) = 4
2x + 12 = 4
2x = 4 - 12
2x = -8
x = -8 : 2
x = -4
nilai x = -4
nilai y = 4
maka, HP = { -4 , 4 }
