penyelesaian dari sistem persamaan{2x+3y=11{5x+3y=23 adalah

MAPEL = MATEMATIKA
KELAS = 8
BAB = SPLDV

eliminasi nilai y
2x + 3y = 11
5x + 3y = 23
__________-
-3x = -12
x = -12/-3
x = 4

subtitusi nilai x
2x + 3y = 11
2(4) + 3y = 11
8 + 3y = 11
3y = 11 - 8
3y = 3
y = 3/3
y = 1

hp = { 4,1 }

semoga membantu

2x + 3y = 11
5x + 3y = 23
____________ +
7x = 34
x = 34/7

2x + 3y = 11
68/14 + 3y = 11
3y = 11 - 68/14
3y = 154/14 - 68/14
3y = 86/14

y = 86/14 × 4/1
y = 172/7
