plis jawab pertanyaan ini dengan spldv 2x-y+4=0 dan 6x+3y+7=0 plis jawab yang lengkap pakai eliminasi

2x-y+4 = 0 >> 2x-y = -4
6x+3y+7 = 0 >> 6x + 3y = -7

2x - y = -4 |×3
6x + 3y = -7 |×1

6x - 3y = -12
6x + 3y = -7
__________-
-6y = -5
y = 5/6

2x - y = -4
(subtitusikan nilai y)
2x - (5/6) = -4
2x = -4 + 5/6
2x = -24/6 + 5/6
2x = -19/6
x = -19/12
