3×+2y=17 dan 2×3y=8 persamaannya adalah

MAPEL = MATEMATIKA
KELAS = 8
BAB = SPLDV

eliminasi nilai x
3x + 2y = 17 |×2
2x + 3y = 8 |×3

6x + 4y = 34
6x + 9y = 24
__________-
-5y = 10
y = 10/-5
y = -2

subtitusi nilai y
3x + 2y = 17
3x + 2(-2) = 17
3x - 4 = 17
3x = 17 + 4
3x = 21
x = 21/3
x = 7

HP = { 7,-2}
semoga membantu
