x²+y² = 5
x²+y²+2x=7
-------------------- -
-2x = -2
x = 1
masukkan ke salah satu persamaan :
x²+y² = 5 <= x = 1
1²+y² = 5
y² = 4
y = 2 atau -2
HP = {1,2} atau {1,-2}

x² + y² + 2x = 7
--------------------------- -
-2x = -2
x = 1
Substitusikan(x = 1)ke persamaan :
x² + y² = 5
(1)² + y² = 5
1 + y² = 5
y² = 5 - 1
y² = 4
y = √4
y = 2
Jadi, HP : (1, 2)
