Hp dari 8x-5y=6 dan 2x+3y=10

MATEMATIKA
PLDV

1) Eliminasi
8x - 5y = 6
2x + 3y = 10

8x - 5y = 6
4(2x + 3y) = 4(10)

8x - 5y = 6
8x + 12y = 40
-------------------- (-)
- 17y = - 34
17y = 34
y = 34 ÷ 17 = 2

2) Substitusi
8x - 5(2) = 6
8x - 10 = 6
8x = 6 + 10 = 16
x = 16 ÷ 8 = 2

3) Hasil
x = 2
y = 2
HP = {2, 2}

Semoga bisa membantu! :DD
