tentukan himpunan penyelesaian sistem persamaan dari -3x+2y=-11 dan 4x-5y=3 dengan menggunakan metode eliminasi

MAPEL = MATEMATIKA
KELAS = 8
BAB = SPLDV

eliminasi nilai x dengan pers. 1 dikali 4 & pers. 2 dikali 3

-3x + 2y = -11 |×4
4x - 5y = 3 |×3

-12x + 8y = -44
12x - 15y = 9
____________+
-7y = -35
y = -35/-7
y = 5

eliminasi nilai y dgn pers. 1 dikali 5 & pers. 2 dikali 2

-3x + 2y = -11 |×5
4x - 5y = 3 |×2

-15x + 10y = -55
8x - 10y = 6
___________+
-7x = -49
x = -49/-7
x = 7

HP = { 7,5 }

semoga membantu

Metode Eliminasi
-3x + 2y = -11
4x - 5y = 3

eliminasi x
-3x + 2y = -11 |×4| -12x + 8y = -44
4x - 5y = 3 |×3| 12x - 15y = 9
_______________________ +
-7y = -35
y = 5

eliminasi y
-3x + 2y = -11 |×5| -15x + 10y = -55
4x - 5y = 3 |×2| 8x - 10y = 6
_________________________ +
-7x = -49
x = 7

Hp = {(5, 7)}
