Verified answer
3x + 4y = 25x + 2y = 8
(3x + 4y = 2) × 1
(5x + 2y = 8) × 2
3x + 4y = 2
10x + 4y = 16
__________ _
- 7x = - 14
x = 14/7
x = 2
3x + 4y = 2
6 + 4y = 2
4y = 2 - 6
4y = - 4
y = - 4/4
y = - 1
Jawaban : a. 2, - 1
Maaf Kalau Salah
3x+4y=2 |×1|
5x+2y=8 |×2|
3x+4y=2
10x+4y=16
--------------- -
-7x = -14
x= -14/-7
x= 2
3x+4y=2
6+4y=2
4y=2-6
4y= -4
y= -4/4
y= -1 -------- A. (2,-1)
JADIKAN JAWABAN TERBAIK YA SEMOGA MEMBANTU
