3x+2y=7 2x+5y=11 spldv dengan mengunakan Cara eliminasi

Matpel : Matematika
Kelas : 8 SMP
Bab : SPLDV

Jawaban :
3x + 2y = 7 pers 1
2x + 5y = 11 pers 2
pers 1 × 2 = 6x + 4y = 14
pers 2 × 3 = 6x +15y = 33
Pers 2 - pers 1 = 11y = 19
y = 19/11

3x + 2y = 7 pers 1
2x +5y = 11 pers 2
Pers 1 × 5 = 15x + 10y = 35
Pers 2 × 2 = 4x +10y = 22
Pers 1 - pers 2 = 11x = 13
x = 13/11
