2x+3y =6 2+3y = 12 kerjakan dengan metode subtitusi, eliminasi, dan gabungan

2x + 3y = 6
2 + 3y = 12

Subtitusi:
2 + 3y = 12
3y = 12 - 2
y = 10/3

2x + 3y = 6
2x + 3(10/3) = 6
2x = 6 - 10
x = -4/2
x = -2


Eliminasi & Gabungan

2x + 3y = 6
2 + 3y = 12
---------------- -
2x - 2 = -6
2x = -6 + 2
2x = 4
x = 2

2x + 3y = 6
2(2) + 3y = 6
4 + 3y = 6
3y = 6 - 4
3y = 2
y = 2/3

Maaf kalau benar ya kak, soalnya dikelas memang saya gak terlalu cerdas.
