2x + 5y = 16 3x – 2y = 5

Jawaban:

2x+5y=16

3x-2y=5

•Eliminasi

2x+5y=16 –>×3

3x-2y =5 –>×2

6x+15y=48

6x-4y=10

—-‐———— –

19y= 38

y=2

2x+5y=16

2x+5(2)=16

2x=16-10

2x=6

x=3

Jawab: x = 3, y = 2

Penjelasan dengan langkah-langkah:

2x + 5y = 16 | ×2

3x – 2y = 5 | ×5

4x + 10y = 32

15x – 10y = 25

———————- +

19x = 57

x = 57/19

x = 3

Subsi :

2x + 5y = 16

2(3) + 5y = 16

6 + 5y = 16

5y = 16 – 6

5y = 10

y = 10/5

y = 2

Jadi HP { 3,2 }
