Diketahui sistem persamaan Linear 5x - 4y = -1 dan 10x + 2y = 3. Penyelesaian sistem persamaan tersebut adalah.....

5x - 4y = -1 (x1)
10x + 2y = 3 (x2)

5x - 4y = -1
20x + 4y = 6
----------------- +
35x = 5
x = 5/35
x = 1/7

5x - 4y = -1
5(1/7) - 4y = -1
5/7 - 4y = -1
-4y = -1 - 5/7 (x7)
28 y = -7 - 5
28y = -12
y = -12/28 (:4)
y = -3/7
