hasil eleminasi 4x-3y-15=0 dan 6x+9y+9=0

4x -3y = 15
6x+9y = -9 disederhanakan mjd 2x+3y = -3
lalu d eliminasi mjd 6x= 12
x = 2

2x+3y = -3
2.2+ 3y = -3
4+3y = -3
3y = -3-4
3y = -7
y = -7/3

4x-3y-15=0
6x+9y+9=0

4x - 3y = 15
6x + 9y = -9 (bagi 3)

4x - 3y = 15
2x + 3y = -3
---------------- +
6x = 12
x = 12/6
x = 2

2x + 3y = -3
2.2 + 3y = -3
4 + 3y = -3
3y = -3-4
3y = -7
y = -7/3

semoga membantu.
