= 7 I kali 2 I ⇒ = 14
--------------------------------- +
= 7
x = 14/7
x = 2
= - 7
+ = - 7
1 + = - 7
= - 7 - 1
= - 8
y = - 4/8
y = - 1/2
Sehinga merubah persamaan menjadi, lalu eliminasi:
2a + 4b = -7 |x1|
6a - 2b = 7 |x2|
Yang menghasilkan:
-7 = 2a + 4b
14 = 12a - 4b +
7 = 14a
a = 1/2
Untuk nilai b, substitusi ke salah satu persamaan:
-7 = 2a + 4b
-7 = 2(1/2) + 4b
-7 = 1 + 4b
4b = -7 - 1
4b = -8
b = -2
Oleh karena itu:
a = 1/2
1/x = 1/2
x = 2
b = -2
1/y = -2
y = -1/2
Sehingga, HP = {(x,y) | (2,-1/2)}
