yang tau tolong bantu jawab yaa

5x + 2y = 16   (x3)
2x + 3y = 2     (x2)
---------------------------
15x + 6y = 48
4x + 6y = 4
--------------------------- -
11x = 44
x = 4

2x + 3y = 2
2(4) + 3y = 2
8 + 3y = 2
3y = 2 - 8
3y = -6
y = -2

maka nilai xy = 4.(-2) = -8
Jawabannya C

5x + 2y = 16 ------- (×3)
2x + 3y = 2 -------- (×2)

15x + 6y = 48
4x + 6y = 4
__________-
11x = 44
x = 4

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

xy = 4(-2)
xy = -8

opsi C

semoga berguna +_+
