Tolong di jawab ya...himpunan penyelesaian dari sistem persamaan {2×-5y=-2 {-3×+4y=-4

Kelas 8 Matematika
Bab SPLDV

2x - 5y = -2 → dikali 3 → 6x - 15y = -6
-3x + 4y = -4 → dikali 2 → -6x + 8y = -8

6x - 15y = -6
-6x + 8y = -8
------------------- +
-7y = -14
y = -14/-7
y = 2

2x - 5y = -2
2x - 5 . 2 = -2
2x = -2 + 10
x = 8/2
x = 4

HP = { (4, 2) }
