tentukan hp dari x + 2y = 4 dan 3x + y = 7 menggunakan metode gabungan. sekarang ya

Eliminasi

x + 2y = 4 (1). x + 2y = 4
3x + y = 7 (2). 6x + 2y = 14

-5x = -10
x = -10 : -5
x = 2

substitusi

x+2y = 4
2 + 2y = 4
2y = 4-2
2y = 2
y = 2 : 2
y = 1

hp ( 2,1)

semoga membantu

Hp 1 = x + 2y = 4 x3 jadinya 3x + 6y = 12
Hp 2 = 3x + y = 7 x1 jadinya 3x + y = 7
__________ -
5y = 5
y = 5/5
y = 1

Hp 1 = x + 2y = 4
Hp 1 = x + 2.1 = 4
Hp 1 = x + 2 = 4
Hp 1 = x = 4-2
Hp 1 = x = 2

Semoga membantu
