Tentukan penyelesaian sistem persamaan berikut dengan metode eliminasi 4x=5y+13 dan 3y=7-5x

Materi : SPLDV

4x - 5y = 13 ..... ×3
5x + 3y = 7 ...... × 5
◆◆◆◆◆◆◆◆◆◆◆◆◆◆
12x - 15y = 39
25x + 15y = 35
◆◆◆◆◆◆◆◆◆◆◆◆◆ [+]
37x = 74
x = 2

4x - 5y = 13
4(2) - 5y = 13
8 - 5y = 13
-5y = 13 - 8
-5y = 5
y = -1

Hp = { 2 , -1 }
