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

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

$3x + y = 5 \ 2x - y = 10 \ 5x = 15 \ x = 15 div 5 \ x = 3$
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:)
