Metode Eliminasi

Mencari nilai x
2x + 4y = -6
3x + 2y = 0

2x + 4y = -6
6x + 4y = 0
------------------ (-)
- 4x = - 6
x = -6/-4 = 6/4 = 3/2

Mencari nilai y
2x + 4y = -6
3x + 2y = 0

6x + 12y = -18
6x + 4y = 0
-------------------- (-)
8y = -18
y = -18/8 = -9/4 = - 9/4

HP = (x, y) = (3/2, - 9/4)

Semoga bisa membantu. :DD
