Penyelesaian SPLDV tersebut adalah x = 1 dan y = 2
Penjelasan dengan langkah-langkah :
2x + 3y = 8 … pers (1)
4x + 5y = 14 … pers (2)
`Eliminasi variabel x
2x + 3y = 8 |×2| 4x + 6y = 16
4x + 5y = 14 |×1| 4x + 5y = 14
__________ -
y = 2
`Eliminasi variabel y
2x + 3y = 8 |×5| 10x + 15y = 40
4x + 5y = 14 |×3| 12x + 15y = 42
____________ -
-2x = -2
x = 1
