3x - 2y + 4 = 0 ⇒ 3x - 2y = -4
3x + 2y = 16 ⇒ 3x + 2y = 16
----------------------- +
6x = 12
x = 12/6 = 2
3x + 2y = 16 ⇒ 3. 2 + 2y = 16
2y = 16-6
y = 10/2 = 5
jadi HP = {2,5}

3x = -y -10 ⇒ 3x + y = -10 l x3 l 9x + 3y = -30
2x + 3y + 16 = 0 ⇒ 2x + 3y = -16 l x1 l 2x + 3y = -16

7x = - 14
x = -14/2 = -2
jadi x = -2
