Sistem persamaan linier 2x-y=1dan 3x-5y=-16mempunyai himpunan penyelesaian

MAPEL = MATEMATIKA
KELAS = 8
BAB = SPLDV

eliminasi nilai y
2x - y = 1 |×5
3x - 5y = -16 |×1

10x -5y = 5
3x - 5y = -16
__________-
7x = 21
x = 21/7
x = 3

subtitusi nilai x
2x - y = 1
2(3) - y = 1
6 - y = 1
-y = 1 - 6
-y = -5
y = -5/-1
y = 5

hp = { 3,5 }

semoga membantu

SPLDV

2x - y = 1
y = 2x - 1

3x - 5y = -16
3x - 5(2x - 1) = -16
3x - 10x + 5 = -16
-7x = -16 - 5
x = -21/-7
x = 3

y = 2x - 1
y = 2.3 - 1
y = 6 - 1
y = 5

HP (x,y) = {(3,5)}
