Tentukan HP dari 2x - 3y = 10 3x + 2y = -3

Gunakan Metode Eliminasi
2x - 3y = 10 ----- (×3)
3x + 2y = -3 ----- (×2)

6x - 9y = 30
6x + 4y = -6
_________-
-13y = 36
y = 36 : (-13)
y = - 36/13

Gunakan Metode Subtitusi
2x - 3y = 10
2x - 3(- 36/13) = 10
2x + 108/13 = 10
2x = 10 - 108/13
2x = (130 - 108) / 13
x = 22 / (13 × 2)
x = 22 / 26
x = 11/13

HP {11/13 , -36/13}

semoga berguna +_+
