Sistem persamaan 5x + 3y = 7 dan 3x – 5y = -23 mempunyai penyelesaian {x, y}, nilai x.y =
jawab asal report​

JAWABAN & CARANYA

SPLDV

Eliminasi X :

5x + 3y = 7 | ×3 | 15x + 9y = 21

3x - 5y = -23 | ×5 | 15x - 25y = -115

___________________________________-

34y = 136

y = 136 ÷ 34

y = 4

Eliminasi Y :

5x + 3y = 7 | ×5 | 25x + 15y = 35

3x - 5y = -23 | ×3 | 9x - 15y = -69

____________________________________-

16x = 104

x = 104 ÷ 16

x = 6,5

Hp (x,y) = (6,5 dan 4)

Nilai x.y = 6,5 × 4 = 26

semoga membantu ya.....
