4x + 2y = 6

2y = 6 – 4x

y = 3 – 2x

Jika x = -1, maka y = 3 – 2 . -1 = 3 + 2 = 5

Jika x = -2, maka y = 3 -2 . -2 = 3 + 4 = 7

Jika x = 0, maka y = 3 – 2 . 0 = 3 – 0 = 3

Jika x = 1, maka y = 3 -2 . 1 = 3 - 2 = 1

Jika x = 2, maka y = 3 -2 . 2 = 3 – 4 = 1

Jika x = 3, maka y = 3 -2 . 3 = 3 – 6 = -3
