3x - 2y = 4 …(pers. 1)
x + 2y = 4 –> x = 4 - 2y …(pers. 2)
substitusi pers. 2 ke pers. 1
3x - 2y = 4
3(4 - 2y) - 2y = 4
12 - 6y - 2y = 4
12 - 8y = 4
-8y = 4 - 12
-8y =-8
y = 1
substitusi nilai y ke pers. 2
x = 4 - 2y
x = 4 - 2 x 1
x = 4 - 2
x = 2
HP = {2 , 1}

X+2y = 4
Ditambah untuk menghilangkan y
3x + x = 8
4x = 8
X = 2
Masukkan x = 2 ke persamaan X + 2Y = 4
2 + 2Y = 4
2Y = 2
Y = 1
X = 2 dan Y = 1
