2x+3y=-1 dan 4x+3y=7

2x + 3y = -1
4x + 3y = 7
----------------- -
-2x = -8
x = -8/-2
x = 4

2x + 3y = -1
2 (4) + 3y = -1
8 + 3y = -1
3y = -9
y = -9/3
y = -3

HP = {(4,-3)}

Bab SPLDV

4x + 3y = 7
2x + 3y = -1
----------------- -
2x = 8
x = 8/2
x = 4

4x + 3y = 7
4 . 4 + 3y = 7
3y = 7 - 16
y = -9/3
y = -3

Maka,
x = 4
y = -3
