2x - 4y = 6 | x1 | 2x - 4y = 6
x + 2y = 11 | x2 | 2x + 4y = 22 _
-8y = -16
y = -16/-8
y = 2
Masukkan y,
2x - 4y = 6
2x - 4(2) = 6
2x - 8 = 6
2x = 6 + 8
2x = 14
x = 14/2
x = 7
Jadi, HP = {7, 2}
c)
4x + 2y = 2 | x1 | 4x + 2y = 2
2x - 3y = 5 | x2 | 4x - 6y = 10 _
8y = -8
y = -8/8
y = -1
Masukkan y,
4x + 2y = 2
4x + 2(-1) = 2
4x - 2 = 2
4x = 2 + 2
4x = 4
x = 4/4
x = 1
Jadi, HP = {1, -1}
