Himpunan penyelesaian dari persamaan berikut. 5x - 4y = -1 10x + 2y = 3

5x - 4y = -1 ...x2
10x + 2y = 3 ...x1
______________

10x - 8y = -2
10x + 2y = 3
__________-
-10y = -5
y = -5 / -10
y = 1/2

Lalu subtitusikan nilai y ke persamaan manapun.

5x - 4y = -1
5x - 4 (1/2) = -1
5x -2 = -1
5x = -1 + 2
5x = 1
x = 1/5
