3x+y =5 2x-y =10 Hp..

[tex]3x + y = 5 \\ 2x - y = 10 \\ 5x = 15 \\ x = 15 \div 5 \\ x = 3[/tex]
jadi, hp=3

-menghilangkan x
3x+ y= 5 || ×2 || 6x+ 2y= 10
2x- y = 10 || ×3 || 6x- 3y = 30
----------------- -
5y= -20
y= -20/5
y= -4

-menghilangkan y
3x+y =5 || ×1 || 3x+y =5
2x-y =10|| ×1 || 2x-y =10
------------- -
x = -5

HP= {( -4,-5 )}

maaf kalau salah:) semoga membantu:)
