tolong dengan caranya

MAPEL = MATEMATIKA
KELAS = 8
BAB = SPLDV

eliminasi nilai x
2x + 5y = -4 |×2
4x - y = 14 |×1

4x + 10y = -8
4x - y = 14
__________-
11y = -22
y = -22/11
y = -2

subtitusi nilai y
2x + 5y = -4
2x + 5(-2) = -4
2x - 10 = -4
2x = -4 + 10
2x = 6
x = 6/2
x = 3

HP = {3,2} ➡D.

semoga membantu
