Tolong di jawab pembahasannya.

2x + y = 8........ 1
3× + 2y = 12......2

1 × 2 = 4× + 2y = 16.......3

3-2 x = 4

masukin ke 1

2x4 + y = 8

8+0=8

y=0

maka 2x-y = 2×4 + 0 = 8

Jawabannya D

2x + y = 8 ----> 4x + 2y = 16
3x + 2y=12----> 3x + 2y = 12
_________-
x. = 4
4 (4) + 2 y = 16
16 + 2y =16
2y = 0
y = 0

2x - y = 2(4) -0 = 8
