Sistem Persamaan Linier
Soal
X+4y=10
3x+6y=18
Tentukan x dan y

Answer 1

Verified answer

Persamaan Linear Dua Variabel

X + 4y = 10
<=> 3 (X + 4y) = 3 x 10
<=> 3X + 12y = 30

Gunakan sistem eliminasi
3X + 12y = 30
3X + 6y = 18
___________ _
6y = 12
y = 12/6
y = 2

Gunakan substitusi
X + 4y = 10
X + 4 x 2 = 10
X + 8 = 10
X = 10 - 8
X = 2

Jadi nilai X = 2
nilai y = 2
