2x + 3y = 11
3x – 2y = -3
Jawab: x = 1, y = 3
Penjelasan dengan langkah-langkah:
2x + 3y = 11 | ×2
3x – 2y = -3 | ×3
4x + 6y = 22
9x – 6y = -9
—————— +
13x = 13
x = 13/13
x = 1
Subsi :
2x + 3y = 11
2(1) + 3y = 11
2 + 3y = 11
3y = 11 – 2
3y = 9
y = 9/3
y = 3
Jadi HP { 1,3 }
Jawaban:
2x+3y=11 (×3)
3x-2y=-3 (×2)
6x+9y=33
6x-4y=-6
—————- –
13y=39
y=3
2x+3y=11
2x+3(3)=11
2x=11-9
2x=2
x=1
HP {1,3}
