2x - 3y = 8 ... (2)
Eliminasi persamaan (1) dan (2)
3x - y = 5 | x 2 | 6x - 2y = 10
2x - 3y = 8 | x 3 | 6x - 9y = 24 ₋
7y = - 14
y = -14/7
y = - 2
Substitusi y = - 2 ke persamaan (1)
3x - y = 5
3x - (- 2) = 5
3x + 2 = 5
3x = 5 - 2
3x = 3
x = 3/3
x = 1
2x-3y=8(*3) 6x-9y=24
----------(-)
7y=-14
y=-2
3x-y=5
3x-(-2)=5
3x+2=5
3x=5-2
3x=3
x=1
jadi x=1 dan y=-2
