2x + y = 4..........pers.1
3y - x + 9 = 0
x - 3y = 9.......pers.2
Menggunakan metode eliminasi.
2x + y = 4...Ix1
x - 3y = 9....Ix2
------------- -
2x + y = 4
2x - 6y = 18
--------------- -
7y = -14
y = -14/7
y = -2
Maka untuk mencari x dimasukkan ke pers.1
2x + (-2) = 4
2x - 2 = 4
2x = 6
x = 3
Jadi HPnya adalah (3,-2)
