————————————————————
2x + 3y = 8
6x + 9y = 24

Kalo di kurangkan hasilnya = 0
Maka :
2x + 3y = 8
2 + 3y = 8
3y = 8 - 2
3y = 6
y = 6 / 3
y = 2 ✔️

6x + 9y = 24
6x + 9( 2 ) = 24
6x + 18 = 24
6x = 24 - 18
6x = 6
x = 6 / 6
x = 1 ✔️

Hp = {(1, 2)}

2x + 3y = 8 → Kali 3
6x + 9y = 24 → Kali 1

⏩Jika Dikurangkan, persamaan diatas akan menghasilkan nilai 0

Maka,

2x + 3y = 8
2 + 3y = 8
3y = 8 - 2
3y = 6
y = 6/3
y = 2

⏩Tentukan Nilai x

6x + 9y = 24
6x + 9(2) = 24
6x + 18 = 24
6x = 24 - 18
6x = 6
x = 6/6
x = 1
