Question

Hasil dari -2x + 4y = -6 dan 3x + 2y =0 menggunakan metode eliminasi

Answer 1

-2x+4y=-6{1}
3x+2y=0{2}
=-2x+4y=6
    6x+4y=0
=-4x=-6
x=6:4
x=1.5

Answer 2

Mencari nilai x:
-2x + 4y = -6 (dikali 1)
3x + 2y = 0 (dikali 2)

Maka:
-2x + 4y = -6
6x + 4y = 0
(dikurangkan)
-8x = -6
x = -6/-8
x = 3/4

Mencari nilai y:
-2x + 4y = -6 (dikali -3)
3x + 2y = 0 (dikali 2)

Maka:
6x - 12y = 18
6x + 4y = 0
(dikurangkan)
-16y = 18
y = 18/-16
y = 9/-8
