eliminasi dari persamaan 2x+3y=13 dan x-5y=0

Menyelesaikan persamaan dengan metode Eliminasi

2x + 3y = 13 |×1|
x - 5y = 0 |×2|

2x + 3y = 13
2x - 10y = 0
..........................-
13y = 13
y = 1

2x + 3y = 13 |×5|
x - 5y = 0 |×3|

10x + 15y = 65
3x - 15y = 0
..............................+
13x = 65
x = 5

Eliminasi x
2x + 3y = 13 (dikali 1)
x - 5y = 0 (dikali2)

2x + 3y = 13
2x - 10y = 0
__________ -
13y = 13
y = 13/13
y = 1

Eliminasi y
2x + 3y = 13 (dikali 5)
x - 5y = 0 (dikali 3)

10x + 15y = 65
3x - 15y = 0
___________ +
13x = 65
x = 65/13
x = 5
