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

5x - 4y = - 1
5x = 4y - 1

10x + 2y = 3
(2 . 5x) + 2y = 3
2(4y - 1) + 2y = 3
8y - 2 + 2y = 3
8y + 2y = 3 + 2
10y = 5
y = 5/10
y = ½

5x = 4y - 1
5x = 4(½) - 1
5x = 2 - 1
x = 1/5

hp = {1/5 , ½}

5x   -  4y =-1 |X2| 10x  -  8y = -2
10x + 2y = 3 |X1| 10x  + 2y =  3
                           _____________-
                                     -10y = -5
                                          y = 1/2
10x + 2y = 3
10x  + 1 = 3
10x = 2
x = 1/5
