Dengan metode eliminasi tentukan: 5× - 4y =-1 dan 10× + 2y =3
![]()
5x - 4y = -1 ..... pers 1
10x + 2y = 3 ..... pers 2
Eleminasi y pers l dan 2
5x - 4y = -1 |×1|
10x + 2y = 3 |×2|
5x - 4y = -1
20x + 4y = 6
-------------------- (+)
25x = 5
x = 5/25
x = 1/5
Eleminasi x pers l dan 2
5x - 4y = -1 |×2|
10x + 2y = 3 |×1|
10x - 8y = -2
10x + 2y = 3
----------------- (-)
-10y = -5
y = -5/-10
y = 5/10
y = 1/2
