Diketahui sistem persamaan linear 5x - 4y = -1 dan 10x + 2y = 3 penyelesaian sistem persamaan tersebut adalah

5x - 4y = -1 |2| 10x - 8y =-2
10x + 2y= 3 |1| 10x + 2y = 3 -
------------------
-10y = -6
y = 6/10
y = 3/5
10x + 2y= 3
10x + 2 . 3/5 = 3
10x + 6/5 = 3
10x = 3 - 6/5
10x = 45/15 - 18/15
10x = 27/15
10x = 9/5
x = 9/5 : 10
x = 9/5 . 1/10
x = 9/50
